Descartes
|
(1596-1650):
-Descartes first recognized brain as “machine” with separate parts. |
|
Neuroscience
|
Multidisciplinary investigation of the nature, function, and origins of the nervous system.
|
|
Neurocorrelates of behavior
|
a method of study that searches for specific mechanism for specific behaviors
|
|
Clinical techniques
|
Link physical brain abnormality with behavior
|
|
Broca’s Area
|
damage of Broca’s area results in impaired speech generation
|
|
Wernicke’s Area
|
Damage to Wernicke’s area results in impaired comprehension.
|
|
Invasive techniques
|
-lesion studies-brain tissue is destroyed or removed and the effects on behavior are observed
|
|
MRI
|
MRI: anatomy
fMRI: function |
|
TMS
|
a non-invasive technique which “turns-off” a brain mechanism for a short time
|
|
CT
|
series of x-rays, each displaying an image of a thin slice
|
|
PET
|
neurons tagged with some sugar are detected when stimulated
|
|
Cortical structure
|
“thin layer of gray matter, consisting of densely packed neurons arranged in columns create electrical and magnetic field
|
|
Phrenology
|
Examining bumps that determine ability and behavior
|
|
CNS
|
Brain and spinal cord-->arousal
|
|
PNS
|
All other nerves. Efferent nerves: carrying signals from CNS, and afferent nerves: to the CNS
|
|
somatic division
|
Part of PNS. Efferent : control skeletal muscles. Afferent: carry info from sense organs to the CNS
|
|
Autonomic nervous system
|
Efferent nerves: regulate various body organs. Afferent: bring CNS info about these various internal systems.
|
|
hindbrain
|
Top of spinal cord, controls key life function
|
|
Midbrain
|
Top of hindbrain, coordinating movements and relaying info from the senses
|
|
Forebrain
|
Largest part of human brain, complex thought and language
|
|
Medulla
|
Bottom of hindbrain, controls breathing and blood circulation and maintaining balance
|
|
cerebellum
|
Largest part of hindbrain. Coordinates movement and balance.
|
|
Cortex
|
Thin covering outside of brain; to fit into small places, seen as crinkled structure.
|
|
Frontal Lobes
|
Behind forehead. speaking, muscle movement, planning, judgment
|
|
parietal lobe
|
at the top rear of brain
receives sensory input for touch and body position |
|
Central fissure
|
Divides frontal lobes
|
|
Lateral fissure
|
Bottom edge of fonrtal lobes
|
|
Temporal love
|
Below lateral fissure
sides of your head, just above the ears. involved in hearing |
|
occipital lobe
|
back of the head
involved in vision |
|
thalamus
|
relay station for all sensory information going to the cortex. except smell.
