Week 4 Vocab Flashcards
Limbic system
a complex system of nerves and networks in the brain, involving several areas near the edge of the cortex concerned with instinct and mood. It controls the basic emotions (fear, pleasure, anger) and drives (hunger, sex, dominance, care of offspring).
Amygdala
a roughly almond-shaped mass of gray matter inside each cerebral hemisphere, involved with the experiencing of emotions.
Hypothalamus
a region of the forebrain below the thalamus which coordinates both the autonomic nervous system and the activity of the pituitary, controlling body temperature, thirst, hunger, and other homeostatic systems, and involved in sleep and emotional activity.
Olfactory cortex
cortex essential to our sense of olfaction and an area of cortex that is part of the limbic system.
Hippocampal formation
an “S” shaped cortex, located in the medial temporal lobe, essential for our memory.
Olfactory bulb
a bulb-like terminal expansion of the telencephalon on which the olfactory nerve fibers end.
Parahippocampal gyrus
a key structure, located in the medial temporal lobe, which includes several cortical areas with connections to the hippocampal formation.
Fornix
a vaulted or arched structure in the body.
Declarative or explicit memory
involves conscious recollection of facts or experiences.
Nondeclarative or implicit memory
involves nonconscious learning of skills, habits, or other acquired behaviors.
Working memory
the part of short-term memory that is concerned with immediate conscious perceptual and linguistic processing.
Remote memory
long term memory often examined by asking the patient their previous address or about well-known past news events they lived through.
Recent memory
memory that should be examined by giving the patient several words to remember and then testing for recall of these words 4-5 minutes later.
Anterograde amnesia
impaired memory of new facts and events occurring after lesion onset.
Retrograde amnesia
impaired memory of events for a period of time immediately before lesion onset, with relative sparing of earlier memories.
