Central Nervous System Flashcards
Brain imaging
Ct scan, cat, mri, used for abnormal masses. Use radioactive dye
Electrical recording
Electrodes put on scalp. Can use to monitor seizure activity and sleep. Can be put into brain because the brain has no pain sensors
Accidents
Phineas Gage and the head injury and how it affected him
Neuropsychological test
Tests tension and memory. Woodcock Johnson (wj3) looks at reading/writing, memory, processing and attention in relation to accidents
Reticular formation
Runs through core. Attention arouses, filters out
Ex: keeps you on task
Thalamus
Relay stations. Takes information and redirects it for processing
Ex: tree to the left
Cerebellum
Memory, functions, time
Ex:remembering how to drive
Brain stem
Central core of the brain. Beginning where spinal cord swells. Responsible for automatic survival functions
Medulla
Heart rate, respiration
Ex: breathing
Pons
Breathing, sleeping
Ex: remembering to breathe while driving
Hypothalamus
Linked to emotion and reward. Directs activities such as eating drinking and body temperature
Ex:turn on air conditioning
Amygdala
Linked to emotion mostly negative
Ex: road rage
Hippocampus
Memory. Short term to long term
Ex: remembers where to go while driving
Corpus callosum
Fibers connecting hemispheres
Ex: communicates what you see and do to the corresponding side of the brain
Frontal lobe
Personality, executive functions, planning , judging, impulse control
Ex: gambling
Motor strip ( cortex)
Allows movement on opposite side of the body. Fibers crossing over
Ex: right hand for gear shift
Broca’s area
Speech. Damage to it will influence articulation and small grammatical words
Parietal lobes
Behind the frontal receives sensory input for touch and body position
Ex: feel pressure of brakes or gas
Occipital lobes
At the back. Primary visual cortex
Ex: seeing the road and hazards
Temporal lobes
On the side. Primary auditory cortex
Wernickes area
Comprehension of speech on the left side
