-
a collection of different structures that encircle the thalamus, more primitive area of the brain
limbic system
-
the part of the limbic system that is involved in forming memories, one in each hemisphere
hippocampus
-
is situated on the ends of the hippocampus, responisble for processing emotional info, in the limbic system
amygdala
-
a cortical area where the hippocampi and amygdala are located, in the limbic system
medial temporal lobe
-
is involved in decision-making, error detection, expectation of reward and emotional pain, in the limbic system
cingulate cortex
-
a collection of three nuclei in each hemispherem lateral to the thalamus, all three structure are involved in skeletal movement,in the limbic system
basal ganglia
-
from a circle of tissue that surrounds the putamen, in the limbic system
caudete
-
in the limbic system,sandwiched medial to the putamen and lateral to the thalamus
globus pallidus
-
the left and right hemispheres of the brain, have a gray matter surface that is 3 mm thick
cerebrum
-
the outermost surface of the cerebrum, has 6 layers of types of cell bodies dendrites or azons,it is wrinkled with ridges
cerebral cortex
-
large and deep sulci are referred to as
fissures
-
this separates the left and right hemispheres in a midsagittal plane
longitudinal fissure
-
the neurons of the left and right emisoheres directly communicate with each other by way of a large, thick band of myelinated axons called
corpus callosum
-
smaller bands of myelinated axons, it connects the hemispheres at amuch more anterior and inferior location
anterior commissure
-
a prominent feature of the cerebral cortex that demacrates the front and back halves of the brain
central fissure
-
distinguishes the top and bottom halves of the brain
lateral fissure
-
occipital lobe
back of the brain, responsible for processing visual info
-
visual info from eyes are sent to thalamus by optic nerves, then relayed to the very back of the occipital love to the
primary visual cortex
-
the inferior sides of the brain, ventral to the lateral fissures and serve to process auditory info
temporal lobes
-
messages about sound travel from inner ear to thalamus, then relayed to ______, it is hidden in the supperior medial portion of the temporal lobe
primary auditory cortex
-
occupies the dorsal surface of the back half of the brain, posterior to the central fissures, anterior to the occipital lobe, superior to the lateral fissure
parietal lobe
-
somatosensory info
info about senses of touch, temperature , stretch, vibration, and pain
-
the parietal lobe also functions for
analyzing visual , motor, and somatosensory and balance information: to understand where the body is in space
-
the most anterior part of the brain
frontal lobe
-
two major cortical areas within the frontal lobe are
motor cortex and prefrontal cortex
-
motor cortex
a ridge of cortical tirrue immediately anterior to the central fissure and pesterior to the prefrontal cortex, it controls muscle movement
-
prefrontal cortex
the most anterior part of the frontal lobe, responsible or cognitive attributes that distinguish humans from all lower animals
-
executive functions
of the prefrontal cortex, they are the higher order mental process that make humans advance and civilized.
