The Cerebral Cortex Flashcards
Occipital lobe, Parietal lobe, Temporal lobe, and Frontal lobe
It is the outer layer of the brain responsible for higher brain functions such as thinking, perception, memory, and voluntary movements.
Cerebral cortex
The cellular layers on the outer surface of the cerebral hemispheres. It allow communication between the two brain hemispheres.
corpus callosum
anterior commissure
The four lobes in the cerebral cortex named based on the bones that lie over them:
occipital lobe, parietal lobe, temporal lobe, and frontal lobe
It is the posterior (caudal) portion of the cerebral cortex located at the back of the brain.
occipital lobe
It processes ______ information and is part of the visual pathway system.
visual
It is also known as the striate cortex, the primary visual cortex.
True or False
True
Damage to any part of the striate cortex can lead to _______ _____-, impacting a person’s ability to see and process visual stimuli.
cortical blindness
It lies between the occipital lobe and the central sulcus, which is one of the deepest grooves on the surface of the cortex.
parietal lobe
The primary somatosensory cortex or the __________ gyrus is responsible for processing touch sensations and muscle-stretch receptors and joint receptors.
It allows us to perceive and interpret sensations.
postcentral
The parietal lobe handles the positions of our eyes, head, and body too and passes it on to brain areas that control movement.
T or F
True
It is located on the sides of each hemisphere of the brain, near the temples.
temporal lobe
Temporal lob: The primary region responsible for processing _______ information.
auditory
In the _____ hemisphere involved in comprehension of spoken language.
Left
The temporal lobe also contributes to complex aspects of vision.
T or F
True
The temporal lobe is also involved in emotional and motivated behaviors.
T or F
True
Located at the most anterior area, extending to the central sulcus.
frontal lobe
The frontal lobe contains two important regions:
- or primary motor cortex
-
the precentral gyrus
the prefrontal cortex
The primary motor cortex is located just anterior to the central sulcus.
It specializes fine motor movement control on the opposite side of the body.
precentral gyrus
In the most anterior portion and forms a large portion of the brain in large-brained species.
Receives information in all senses.
prefrontal cortex
A controversial procedure that was once used to treat psychological disorders - disconnecting the prefrontal cortex from the rest of the brain.
Prefrontal lobotomy
Due to effective drug therapies prefrontal lobotomy was largely discontinued.
T or F
True
Prefrontal lobotomies often led to significant cognitive and emotional impairments.
T or F
True
The “binding problem” refers to the challenge of understanding how different brain areas work together to create a ______ perception.
single
Research found that only a few cells actually combine different senses.
True or False
True
Single object perception occurs when two sensations are perceived as happening simultaneously and in the same location.
True
