Module 6 Flashcards
What is the cerebral cortex
The surface interconnected neural cells covering the cerebral hemispheres, the bodies ultimate control and information processing center
Where is each of the 4 main lobes
Frontal; behind forehead. parietal; at the top and to rear. occipital; back of head. temporal; just above the ears
How was the motor cortex mapped
Due to the lack of receptors, electrical shocks to different areas revealed answers
If the motor cortex is for sending messages out, what receives messages from the senses
The somatosensory cortex
What do hallucinogenic drugs like LSD provide hallucinations?
The drug intercepts, and increases the communication between the visual cortex and other brain regions, causing high stimulation
Where is the visual cortex?
occipital lobe (back of the brain)
Where is the auditory cortex?
temporal lobe (just above the ears)
How does frontal lobe damage impact personality
It can make someone more agitable, dishonest, profane, and overall less moral
What part of the brain performs mathematical and spatial reasoning?
the parietal lobes
What lobe helps with face recognition
Underside of right temporal lobe
Why are “brain hot spots” and phrenology not great ways to understand the brain?
The brain works in unison in a lot of cases, brain scans show activity of it working together, while some things run automatically in the background. This is known as functional connectivity
What is functional connectivity?
Communication among distinct areas of the brain responsible for memory, language, attention, social skills, etc.
What is neuroplasticity?
The ability of the brain to change in response to experience
Where does the left visual field transmit to?
The right hemisphere
Where does the right visual field transmit to?
The left hemisphere
