Practical Application
Researchers of the mouse
study found that a disruption in maternal care could trigger genetic changes
that set the groundwork for depression in adulthood when confronted by periods
of stress. It also suggested that the priming could be undone by appropriate
intervention at the right time (although specifics were not provided). My
brain’s opinion is that if you uncover your personal history in terms of what
happened to you in childhood, especially related to disruption of maternal
care, it may be possible to reduce one’s risk for adult stress-related
depression. However, you only know what you know and can only do something
about what you know. In my experience, Family-of-Origin work has been
invaluable in helping me better understand early stressors in my life and take
steps to develop valuable management strategies to minimize the occurrence of
depression. More tomorrow.

Stress-Depression Link, 3
Researchers found that disrupting
maternal care of mice produced changes in levels of hundreds of genes regulated by the transcription factor
orthodenticle homeobox 2 (OTX2) in the VTA brain reward center. The good news was that although early
stress could establish the groundwork for later depression, that priming could
be undone by intervention at the right moment. Professor Eric
J. Nestler, who led the mouse study, explained that this “mouse paradigm will
be useful for understanding the molecular correlates of increased risk of
depression resulting from early life stress and could pave the way to look for
such sensitive windows in human studies. The ultimate translational goal of
this research is to aid treatment discoveries relevant to individuals who
experienced childhood stress and trauma.”

Stress-Depression Link, 2
According
to the abstract of a recent study on mice, stress early in life increased a risk for
depression in adulthood. Researchers established what they labelled a two-hit
stress model in mice. Baby mice
that were subjected to stress during a specific postnatal period showed increased susceptibility to adult social-defeat stress. This
appeared to result from long-lasting transcriptional alterations that primed a
brain reward area known as the VTA or ventral tegmental area to be in a
depression-like state. The VTA encoded a lifelong, latent
susceptibility to depression that was revealed only after the now-adult mice
encountered additional stress. Although early childhood stress could establish the groundwork for later
depression, the good news was that this priming could be undone by
intervention. More tomorrow.

Stress-Depression Link
People
often ask: “Tell me the reason you believe that Family-of-Origin (FOO) work is
worth doing.” I can give you my brain’s opinion. First, childhood stress, dysfunction,
trauma, and abuse can bang around in one’s head for a lifetime, negatively
impacting relationships, overall success, and so on. Linking early-in-life
stress with adult behaviors is complex. Dr. Eric J. Nestler
along with Dr Catherine Peña and
colleagues studied mice and childhood stress. They isolated
a time period in early development when mice are
especially susceptible to stress. They also identified a
molecular basis for stress during a sensitive developmental window that programmed a mouse’s response to stress in adulthood. More tomorrow.

Brain & Facial Encoding, 5
“The
way the brain processes this kind of information (facial encoding and recognition) doesn’t have to be a
black box,” said Le Chang. “Although there are many steps of computations
between the image we see and the responses of face cells, the code of these
face cells turned out to be quite simple once we found the proper axes.” If you’re
interested in reading more about this and want to see pictures showing eight
different real faces that were presented to a monkey, together with
reconstructions made by analyzing electrical activity from 205 neurons recorded
while the monkey was viewing the faces, try the URL below.

Brain & Facial Encoding, 4
Researchers discovered that axes within a multidimensional space, now
known as the “face space” can combine in different ways to create every
possible face. In other words, there is no Jennifer
Aniston neuron. Senior author Doris Tsao, a professor of
biology and biological engineering at the California Institute of Technology
reported: “We’ve discovered that this code is extremely simple. We can now
reconstruct a face that a monkey is seeing by monitoring the electrical
activity of only 205 neurons in the monkey’s brain. One can imagine
applications in forensics where one could reconstruct the face of a criminal by
analyzing a witness’s brain activity.” More tomorrow.

Brain & Facial Encoding, 3
Primates recognize complex objects such as faces
with remarkable speed and reliability. Experiments in macaques demonstrated an
extraordinarily simple transformation between faces and responses of cells in
face patches. Six general
areas of the primate and human brain that are responsible for recognizing faces
were identified. Labelled ‘face patches,’ all six face patches were located in
the inferior temporal (IT) cortex. Researchers found that these areas are
packed with specific nerve cells that activate much more strongly when seeing
faces than when seeing other objects. They called these neurons “face cells.” Rather than representing a specific
identity, each face cell represents a specific axis within a multidimensional space, which researchers
called the “face space.” More tomorrow.

Brain & Facial Encoding, 2
In a paper published June 1,
2017 in the journal Cell,
researchers Le Chang and Doris Y. Tsao reported that they have deciphered how faces are
encoded in the brain—at least in primates. Previously, some experts in the field believed that each
face cell (a.k.a. “grandmother cell“) in the brain represents a specific face.
This presented a paradox, according to Doris Y. Tsao, who is also a Howard
Hughes Medical Institute investigator. “You could potentially recognize 6
billion people, but you don’t have 6 billion face cells in the IT or inferior
temporal cortex. There had to be some other solution.” It turns out there was. More

Brain & Facial Encoding/Recognition
Earlier this year I
mentioned the “Jennifer Aniston neuron,” so called, which led some to believe that the representation of an entire face may be filed in
a single neuron. They reportedly touched a single neuron inside a person’s
brain and the patient reported seeing Jennifer Aniston’s face. That flew in the
face of previous beliefs that memory for faces was somewhat diffuse throughout
the brain and that the hippocampus might play a role in searching for pieces to
assemble a ‘face’ much like putting together a jigsaw puzzle. A new study was
recently released that provided some specifics related to facial encoding in a
primate brain. That’s what it so exciting about brain-function research—new
information is released quite regularly! More tomorrow.

Pratfall Effect, 4
To recap: the pratfall effect is a psychological phenomenon that says
your likability actually increases when you make mistakes! Competent people appear more
likeable and attractive when they make a mistake than when they are perceived
as perfect and flawless. No surprise, it is named after an American expression
or slang word for falling on your behind or keister. In
one study, psychologist Elliot Aronson asked research
participants to listen to recordings of people answering a quiz. Select
recordings included the sound of the person knocking over a cup of coffee. When
study participants were asked to rate
the quizzers on likability, the coffee-spill group came out on top. This means
that being real—acknowledging when you make a mistake, apologizing as
indicated, and moving on—may make you look better than an individual who seems
quite flawless due to being perceived as not being as human. Indeed, mistakes
are simply a validation that one is human. Everyone makes mistakes; not
everyone learns from them. Therein lies the rub.

Pratfall Effect, 3
There appear to be some male-female differences in terms of the pratfall effect. This from studies by K. Deaux: “To err is humanizing: But sex makes a difference” Representative Research in Social Psychology, p 3, 20-28, 1972).
In general:
- The effects of pratfall are most directly applicable to males
- Females tend to prefer the non-blunderer regardless of gender
- Neither males nor females preferred the mediocre blunderer
Aronson studied a person’s attractiveness as related to his or her making a blunder. His research found that a perceived ‘able’ individual’s attractiveness increased after a blunder in comparison to the control group; while attractiveness decreased in a person perceived as less ‘able.’ (Attractiveness was defined as a combination of liking and respect.)

Pratfall Effect
The “pratfall effect” appears to be well established in popular culture. It can be
described as the tendency for a person’s attractiveness to increase or decrease
after he or she makes a mistake, depending on the individual's perceived
ability to perform well in a general sense. For example, an individual who is
perceived as highly-competent would be, on average, more likable after
committing a blunder. The individual would tend to be less likable after making
a mistake or faux pas if he or she was perceived as an average person. The pratfall
effect was described by Elliot Aronson in 1966. Since then, a plethora of
studies have been conducted in an attempt to isolate the impact of self-esteem
levels, gender, and the severity of the blunder on perceived changes in
attractiveness or likability. The pratfall effect is also referred to as the blemishing
effect when it is used as a form of marketing. More tomorrow.

Spotlight Effect, 4
What is the bottom line here? Other people
are not paying attention to you nearly as much as you may think they are. Knowing
this can give you permission to be yourself, help you feel less embarrassed in
public when something untoward happens, and take it a bit easier when you do
make a mistake. Kenneth Savitsky put it like this: "You can’t completely
eliminate the embarrassment you feel when you commit a faux pas, but it helps
to know how much you’re exaggerating its impact.” Studies have
shown empirically that a drastic over-estimation of one's effect on others is
widely common. Once you know about the spotlight effect, you can choose to
become more realistic in terms of how much you believe you really are the
center of attention and in a social spotlight. The perception of being under
constant scrutiny is a mind construct, and the self-doubt you feel after making
a mistake appears not to truly reflect reality. That’s good news!

Spotlight Effect, 3
An article by Gilovich, et al,
entitled: “The spotlight effect in social judgment: An egocentric bias in
estimates of the salience of one's own actions and appearance,” (Journal of
Personality and Social Psychology, 78(02), 211–222), pointed out that aspects of social judgment are impacted by the spotlight effect. That is, people routinely
overestimate the extent to which their contributions make an impact on
those around them, especially the significance of one’s ideas and contributions
within a group. Researchers found that in a group setting, contributions by an
individual are perceived by that individual as being more significant than the
contributions of their group members. No surprise, the other members in the
group believe the same thing about their own individual contributions. More

Spotlight Effect, 2
Thomas Gilovich and Kenneth Savitsky reportedly coined
the term “spotlight effect,” in 1999, although behaviors related to this
phenomenon had been described earlier than that. What are some of those
behaviors? When individuals are anxious about something they tend to overestimate
the extent to which their anxiety is obvious to onlookers. When an individual
is embarrassed by something (e.g., a run in one’s stocking, a tear in one’s
shirt), the likelihood of the spotlight effect rearing its head is increased.
The timing of the incident also plays a part. Immediate exposure increases the
spotlight effect, while delayed exposure decreases it. Psychologists
at Cornell University reportedly asked study participants to wear an embarrassing
T-shirt and then estimate how many people noticed what they were wearing. The participant
estimates were twice as high as the actual number. More tomorrow.

Spotlight Effect
Yes, this is real phenomenon that plays a
significant role in many different aspects of society. The term Spotlight
Effect refers to a general perception by people that they are being noticed
much more than they really are. According to some sources, research on this phenomenon has been
pioneered primarily by four individuals: Thomas Gilovich, Kenneth Savitsky,
Victoria Medvec, and Thomas Kruger. The underpinnings of the spotlight effect
is the innate tendency of many individuals to forget that although each person
is the center of his or her own world, that person is not the center of
everyone else’s world. Being that one is constantly
in the center of one's own world, an accurate evaluation of how much one
is noticed by others is uncommon. The spotlight effect may be more pronounced,
however, when a person does something that is not typical behavior for them.

Brain-Body Community
Dr. Bruce Lipton pointed out that if
you were the size of an individual cell so you could see your body from that
perspective, you would see yourself, not as a single entity, but as a bustling
community of more than 50 trillion individual cells. Most of the cell’s
structures are referred to as organelles, which are its ‘miniature organs,’
suspended within a jelly-like cytoplasm. Organelles are the functional
equivalents of the tissues and organs of your own body. Each nucleus-containing
cell (eukaryote) possesses the functional equivalent of your nervous,
digestive, respiratory, excretory, endocrine, skeletal, circulatory, skin, and
immune systems. Groups of specialized cells that form the tissues and organs of
the nervous system, are concerned with reading and responding to environmental
stimuli. The nervous system’s job is to perceive the environment and coordinate
the behavior of all the cells in the vast cellular community.

Brain and Sodas, 4
Sudha Seshadri is a professor of neurology at Boston University School
of Medicine (MED) and a faculty member at the University’s Alzheimer’s Disease
Center. Senior author on both study papers containing data related to drinking
sugary drinks and sodas of any type, Seshadri reportedly said that the study
conclusions make it appear that there is not very much of an upside to having
sugary drinks, and substituting the sugar with artificial sweeteners doesn’t
seem to help. Smaller overall brain volume? Poorer episodic memory? A shrunken
hippocampus? A higher risk for stroke and dementia? Both sugary and diet drinks
are linked with an increased risk of accelerated brain aging? I don’t think so;
not for me. True, research studies do not say anything about a specific individual.
Nevertheless, water is my beverage of choice and part of my Longevity Lifestyle
journey.
