Brain Health and Mindfulness
Today:
• What is this thing called
mindfulness?
• What effect does
mindfulness have on the
way we see the world?
• What are some physical
and psychological
benefits of mindfulness?
• What effect does
mindfulness have on the
brain?
• What effect does
mindfulness have on the
aging brain?
• How can I get some of
that?!
My hope…
– Is that this presentation improves your life, and
that of your patients and colleagues
– Mindfulness promotes caring, compassionate
interaction with patients and colleagues, and my
goal is to make the workplace (and the home
place, for that matter) a mindful place
Mindfulness……
• Mindfulness defined: (Kabat-Zinn, 1994, p. 4)
“Paying attention in a particular way: on purpose, in the present moment,
and non-judgmentally.”
• A key component is “in the present moment”
– Mindfulness allows self reflection
– Self-reflection allows me to decide my reaction to circumstances, events,
other people
– My reaction determines my level of psychological stress
– Mindfulness allows me to make my own decisions about how I am going to
respond, what I am going to do
– The only place decisions happen is in the present moment
• Mindfulness Meditation is a formal practice that allows me to pay
attention, intentionally, non-judgmentally.
Research in Effects of Mindfulness has
Grown Exponentially
Why Would I Want to Meditate?

Neurophysiology of Mindfulness
http://science.nationalgeographic.com/science/health-and-human-body/human-body/mind-brain/
What are the neural underpinnings of
mindfulness?
• The components of mindfulness include
– Focused attention and non-judgmental observation
– Non-judgmental observation of what arises during this focused attention
– Insights that arise from that observation Increased awareness of the body
(body sense) and the individual’s environment and decreased dependence on
judgment
• Predictions: Should see changes related to
–
–
–
–
–
Sustained attention
Cognitive processes
Emotional regulation
Body (Somatic) sense
Judgement
Basic neurophysiology
• Regions of control and processing work
together to accomplish tasks
– e.g. language areas work together to understand
(comprehension) and to express language
(speech)
Most of our areas of interest are
cerebral
• Cerebral cortex
– responsible for virtually all voluntary
motor function and for all conscious
activity
• Lobes of the brain:
– Frontal lobe: cognition (memory,
attention, visual processes, language)
– Parietal lobe: body sense and
integration of sensations with the
sense of body
– Temporal lobe: auditory sense,
language, memory, face recognition
– Occipital lobe: visual sense
– Insula (not shown): sense of self

Our culture is left-focused
• Will always show left
hemisphere, not right
• We value analysis,
attention to detail,
planning, organizing
stimuli
• We devalue anything that
does not include
organization, planning,
and detail
• Hmmm. I wonder if that’s
such a great idea?
(Ipse quod dixit: Latin
for “What I said!”)
Cerebral Hemispheres: Specialization
of function
• Left hemisphere: “Just the
facts, ma’am”
– Grammar and details of
language
– Detail oriented, generally
– Planning
– Organization
– Rapid response
– Analysis
– Left fusiform gyrus
• parts of the face: eyes, nose,
mouth
– Significant pathology: Aphasia
(acquired language deficit)
• Right hemisphere: “Whole
from the Parts”
– Context of language
– Placing detail in context (Larger
picture)
– Not planning!
– Not organizing detail, but
rather seeing the larger view of
how details fit together
– Synthesis
– Slower response
– Right fusiform gyrus
• the face in its totality; facial
recognition
– Significant Pathology:
Hemispatial neglect syndromes
Specific areas to watch in
Mindfulness and
cognition
1. Dorsolateral cortex (DL or
DLPFC) (BA 9, 46)

So what happened when you meditate?
Active areas during mindful meditation are
related to attention…
• Attentional areas are activated
– Right dorsolateral prefrontal cortex
(Lazar et al., 2000)
• Executive Function
– Right insula in novices; left insula in
experts
• (Farb et al, 2007; Lutz et al., 2008;
2009)
• Empathy, self-awareness
– Hippocampus (Lazar et al., 2000)
• Memory, attention
– Right Inferior frontal gyrus and TPJ
(attentional) (Pagnoni, 2012)
• Attention (note hemispatial neglect)
Temporoparietal
junction (TPJ)
The Cycle of Meditation
•
Ability to focus is limited
and transient
– Vigilance function
•
Attention goes through 4
identified cycles
– Focus:
•
Right dorsolateral
prefrontal cortex
– Mind-wandering:
•
R & L Posterior frontal
and ventromedial
posterior cingulate
– Awareness of wandering:
•
R & L Insula, dorsal
anterior cingulate gyrus
– Shift back to focus:
•
•
Right dorsolateral
prefrontal cortex & R
posterior parietal

But What About Aging And Mindfulness:
Does Mindfulness Affect The Aging Brain?
• So what happens when we age?
• At our peak we have incredibly robust
brains
– adult cerebral cortex contains between 20 and
25 billion neurons
– Contains about 18 trillion astrocytes, critically
important for long-term memory
– volume of around 400 cubic centimeters
– one cubic centimeter (1cm x 1 cm x 1cm)
contains 40,000 neurons (Pakkenberg &
Gunderson, 2011).
As we age, things change: Cognition
• Cognition
– Cognitive processes
•
•
•
•
•
Memory
Attention
Visuospatial processes
Linguistic processes
perception
– As we age, we decline in
memory and executive
function
– We decline in memory
and attention abilities

Brain volume changes as we age: The
cortex gets thinner
The cerebral hemispheres
get thinner as we age…
…as does the
hippocampus

…and this change is seen throughout all of
the cerebral cortex!

volume. Neurobiology of aging, 25(3), 377-396.
The biggest changes in the brain
during aging:
“Of the brain regions affected by ageing, the
hippocampus and the PFC [prefrontal cortex]
seem to be particularly vulnerable, but even
within and between these regions the impact of
ageing on neuronal function can differ…”

From Data of Simic et al., 1997
Meditators Have Greatly Reduced Volume Loss
In The Hippocampus
• Luders et al., 2009
– Meditators had larger hippocampal volumes than non-meditators
• 22 meditators, 30-71 years old
• Significantly greater hippocampal volume in meditators
• Holzel et al., 2008
– 20 meditators, 34.1 years old
– Significantly greater hippocampal volume in meditators
• Pickut et al., 2013
– Increased hippocampus volume in Parkinson’s patients who
meditate compared with treatment-as-usual
• Holzel et al., 2011
– 8 week MBSR course
– Increased volume in hippocampus
“Meditation may slow, stall, or even reverse age-related
brain degeneration.“
-Luders, 2014
Lazar et al., 2005
• 40-50 year old meditators’ brains
were the same thickness as 20-30
year olds
• Right Frontal lobe: Executive function
(BA 9,10), emotion regulation
Pagnoni and Cekic, 2007
• Zen meditators
• Putamen volume remains
essentially as meditator ages
• putamen involved in
attention
• Reaction time remains
essentially the same in
meditators

Meditation and degenerative disease:
Parkinson’s Disease:
• Patients with Parkinson’s
disease compared with
treatment as usual
• Significant improvement
in volume of right and left
hippocampus with
meditation
• Significant amygdala
increase with meditation
From Pickut et al., 2013
What the meditator gains from all
this…
• Is the ability to shift from self- or other-judgment
• Is the ability to hold perception of self as a whole,
and as related to other things and people
• Is the ability to control your own mental
processes:
– when you want to be detail focused, you can choose
– When you want to suspend judgment, you can choose
– When you feel yourself getting distraught, angry,
upset, you can choose
• …and, of course, an improved and younger brain!
Right insular cortex seizures: patient
quotes from Picard, 2013
• “…during my seizures, all of these boundaries would suddenly be
erased. Although all my judgments of shape, size, color, texture,
and so on would remain totally unchanged, the evaluation of my
environment would undergo a sudden transformation. Everything
would be joined together into one whole, as if every single thing in
my surroundings were deliberately placed by an artist with the goal
of composing a photograph. ”
• “One often has (what is sometimes called) an “aha!” moment when
we can suddenly explain several puzzling facts simultaneously with
the same answer. The sense that I had when I was experiencing
some of these seizures was not unlike a continuous series of
profound “aha!” moments. Although nothing around me seemed to
have changed in any concrete way, every observation of my
surrounding environment seemed to “make sense” in this way. ”
Summary
• Long term meditation alters activation of prefrontal cortex related to
attention and self-awareness
– Increased right dorsal prefrontal cortex: attention
– Increased right insula in novices; left insula in experts: perception of selfidentify, empathy, awareness
– Increased activation of right Temporoparietal junction (TPJ): attention,
particularly to body
– Increased activation of hippocampus (attention and memory)
• Meditation alters volume of brain
– Increased brainstem, L hippocampus, TPJ, CC, Rt. VM in experts
– Increased hippocampus, CC, TPJ in brief training
• “Following an intensive 8 week course in mindfulness meditation, during
which individuals learn to develop the capacity to monitor moment-tomoment experience, Experiential focus [condition] resulted in a
pronounced shift away from midline cortices towards a right lateralized
network comprised of the ventral and dorsolateral PFC, as well as right
insula, SII and inferior parietal lobule.” Farb et al., 2007,pg. 319.
