9. Other Brain Functions Flashcards
Receives sensory input and controls muscular activity in the left half of the body
Right cerebral hemisphere
Receives input and control muscles in the right half of the body
Left cerebral hemisphere
Broad band of nerve tracts at the base of longitudinal fissure
Corpus callosum
Located in parietal lobe
Functions in understanding and formulating coherent speech
Sensory speech area (wernicke area)
Located in the frontal lobe
Controls the movement necessary for speech
Motor speech area
Damage to sensory and motor speech area may result in ?
Aphasia- absent or defective speech or language comprehension
Most common cause of aphasia is ?
Stroke
Placed on a person’s scalp and attached to a recording device can record the brain’s electrical activity producing _______
Electrodes
Electroencephalogram (EEG)
EEG patterns can be detected as wavelike patterns known as _______
Brain waves
Type of brain wave that are observed in a normal person who is awake but in a quiet, resting state with the eyes closed
Alpha waves
Type of brain wave that occur during intense mental activity
Beta waves
Type of brain wave that occur during deep sleep, in infants, and in patients with severe brain disorders
Delta waves
Type of brain wave that is usually observed in children but can also occur in adults who are experiencing frustration or who have brain disorders
Theta waves
3 stages of storage of memory
Working
Short term
Long term
The brain briefly stores information requires for the immediate performance of a task
Only lasts few seconds to minutes
Working memory
Lasts longer than working memory
Can be retained for a few minutes or few days
Short term memory
It may be stored for only a dew minutes or become permanent
Length of time memory depends om how often it is retrieved and used
Long term memory
Gradual process involving the formation of new and stronger synaptic connections
Consolidation
Involves the retention of facts such as names, dates, and places
Declarative memory (explicit memory)
Involves the development of motor skills such as riding a bicycle
Procedural memory
Whole series of neurons
Involved in the long term retention of a given piece of information, a thought, or an idea
Memory engrams or memory traces
Influences long term declarative memory, emotions, visceral responses to emotions, motivation and mood
Limbic system
