Transcript Wernicke`s Area

Right Hemisphere:
 Creativity
 Colorful
 Emotion
 Musical
 Art
 Spatial
 Imagination
 Spiritual
relations
 Patterns
 Controls left
side of body
Left Hemisphere:
 Language
 Organization
 Logic
 Analysis
 Math
 Exactness
 Problem
 Details
solving
 Sense of time
 Controls
right
side of body
Corpus Callosum
 Band
of nerves connecting the
two hemispheres
 Allows the hemispheres to
communicate
Fissures
“Wrinkles”
Deepest
grooves in the brain
Central Fissure - divides
hemisphere in half from front to back
Lateral Fissure - runs along the side
of each hemisphere
Frontal Lobe
Located
at the front of the brain in
front of the central fissure
Responsible for PERSONALITY,
EMOTIONS, MEMORY of
experiences, and REASONING
Broca’s Area:
Dr. Paul Broca 1861
Tan
Part
of the brain that allows you
to be able to speak
Located in the left frontal lobe
Motor cortex
Located
at back edge of the frontal
lobe in front of the central fissure
Responsible for processing
voluntary movement for specific
parts of the body - SOMATIC
Parietal Lobe
Located
behind the central fissure
at top back part of brain
Responsible for TOUCH such as
processing temperature, pressure,
pain on the skin
Sensory cortex
Located
on front edge of parietal
lobe behind the central fissure
Responsible for processing
sensations for specific parts of the
body - SOMATIC
Homunculus
Created in the 1950’s
 Dr. Wilder Penfield - ESB
 Cartoon figure to explain the
sensory cortex and motor cortex
 Brain surface area is
proportionate to the frequency
of behavior

Temporal Lobe
Located
in the brain below the
lateral fissure
Responsible for HEARING and
MEMORY of objects
Wernicke’s Area:
Dr. Carl Wernicke 1874
Part
of the brain that allows you to
be able to understand speech
Located in the left temporal lobe
Occipital Lobe
Located
at the very back of brain
Responsible for VISION by
processing shapes, color, and
motion
Invasive techniques
 Removal
 Scarring/
Lesioning
 Research on the hypothalamus in
Rats?
EEG
+ Shows activity of the brain
- Limited information - ????
CAT scan
+ Shows structure of the brain
- Limited information - ????
PET Scan
+ Shows ongoing activity of the brain
- Limited information - ????
fMRI scan
+ Shows activity & structure of a 3D brain
Mirror neurons
 What
are they?
 How can having these be
helpful?
Hormones


Different from neurotransmitters!!!!!
Produced by the glands in the endocrine
system





Pituitary gland, adrenal glands, pancreas, etc.
Adrenaline – fight or flight response
Cortisol – arousal, stress hormone, memory
Oxytocin – the “love hormone”
Melatonin – regulates sleep
