Mapping the brain

Use the following link to find and
describe the functions of the brain


Launch the interactive link.


perspective (coronal, sagittal, axial)

A. Name the part of the brain

B. Draw in a
bright color
the section of the

brain in the proper anatomical location.

C. Describe how it appears on the scan.

Using the information icon, record the main
functions and any other factual observations.



Functional magnetic resonance imaging:
a form of magnetic resonance imaging of the brain that

registers blood flow to functioning areas...

pet scan

Positron emission tomography
(PET) is a nuclear medicine imaging technique which produces a three

dimensional image or picture. For more information click the link



MEG scan
, 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.

Description of function _________________________________


The amygdala is a tiny almond
shaped mass
located deep inside the temporal lobe.

A study in

in 2011 showed that the bigger
your amygdala, the more friends you have.

Brain Stem

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
brain stem.

Broca’s Area

Broca's area refers to a section of cerebral cortex
in the lower portion of the frontal lobe near the
temporal lobe.

It is linked to speech and lies in the dominant
hemisphere, which is on the left
hand side in
most people.


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.

Frontal Lobe

The frontal lobe is both the largest and forward
most lobe of the brain.

It is separated from the

lobe by the
central sulcus

a vertical groove in the cortex

and from the

lobe by another groove
called the
Sylvian Fissure


The hippocampus lies beneath the

of the
temporal lobes.

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
circadian cycles.

Motor Strip

The motor strip, also known as the
motor cortex
, 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

Occipital Lobe

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.

Parietal Lobe

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

be it
language, vision, hearing, pain, movement, or

Prefrontal Cortex

The prefrontal cortex is the forward
most region
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

Sensory Strip

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
motor strip.

Temporal Lobe

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
term memory.


The thalamus is a paired, egg
shaped structure
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

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
