, is an imaging technique that identifies brain activity and measures
small magnetic fields produced in the brain. Of all the brain scanning methods, MEG provides
the most accurate resolution of the timing of nerve cell activity
down to the millisecond. Hopefully, as the
technology improves, MEG devices will become cheaper, more portable, and more prevalent.

The amygdala is a tiny almond
located deep inside the temporal lobe.
A study in
in 2011 showed that the bigger
your amygdala, the more friends you have.
The brainstem is the vertical structure
connecting the spinal cord to the brain.
All motor and sensory communication between
the brain and the body is funneled through the
Broca's area refers to a section of cerebral cortex
in the lower portion of the frontal lobe near the
It is linked to speech and lies in the dominant
hemisphere, which is on the left
hand side in
The cerebellum sits just beneath the cerebrum.
Unlike the undulating and variable ridges and
folds of the cerebrum, the folds in the
cerebellum are much tighter and more regular,
like an accordion.
The frontal lobe is both the largest and forward
most lobe of the brain.
It is separated from the
lobe by the
a vertical groove in the cortex
and from the
lobe by another groove
The hippocampus lies beneath the
Its name is Latin for seahorse, which its shape
One study showed that the area of the
hippocampus that stores navigational memory
was larger in taxi drivers.
About the size of a pearl, the hypothalamus is
located below the thalamus.
It's primarily responsible for controlling body
temperature, hunger, thirst, fatigue, sleep, and
The motor strip, also known as the
, is a thin strip of cortex toward the
back of the frontal lobe that spans both
hemispheres of the brain.
Many musicians have an abnormally large area
of motor cortex dedicated to controlling finger
The occipital lobe, the smallest of the four lobes,
is responsible for vision.
It is less vulnerable to injury than other lobes
thanks to its location at the back of the head.
The parietal lobe lies at the top of the brain,
between the frontal and occipital lobes, and is
primarily responsible for spatial and visual
perception as well as for interpreting
language, vision, hearing, pain, movement, or
The prefrontal cortex is the forward
of the frontal cortex.
Compared to most mammals, humans have an
abnormally large and convoluted prefrontal
Primary Auditory Cortex
The primary auditory cortex is located in the
uppermost part of the temporal lobe.
After adjusting for brain size, women on average
tend to have significantly thicker primary
auditory cortices than men.
Primary Visual Cortex
The primary visual cortex lies in the middle of
both occipital lobes.
It receives information directly from the eyes
and passes it on to other areas of the occipital
lobe for further processing. This is also known as
Brodmann area 17
The sensory strip, located in the parietal lobe,
receives feedback from joints and tendons in the
body and is organized in the same way as the
The left and right temporal lobes sit on the sides
of the brain, in front of the occipital lobe.
They contain most of the limbic system,
including the amygdala and the hippocampus.
The limbic system contains the brain's "pleasure
center" and regulates emotion and motivation. It
also plays a key role in long
The thalamus is a paired, egg
that sits atop the brainstem in the center of the
brain. It plays a role in attention, memory, and
alertness, serving as a major pre
relay station for information going to the cortex
from all the senses except smell.
Wernicke's area consists of a section of cortex in
the temporal lobe.
In 97% of people it is found in the left
In 2012, researchers at Georgetown University
discovered that the area was several centimeters
closer to the front of the brain than previously
