Summary EPPP: Biological Bases of Behavior

EPPP: Biological Bases of Behavior In-class activity Delerium - Acute state of confusion that is abrupt and is usually reversible Parkinson's Disease - Motor disease characterized by shaking, rigidity, slowness of movement, and difficulty walking; caused by lack of dopamine in substantia nigra Korsakoff's Syndrome - A neurological disease resulting in loss of declarative memory, caused by depletion of thiamine, usually due to long-term alcohol abuse Symptoms of Korsakoff's - Anterograde amnesia, retrograde amnesia, confabulation, apathy, limited content in conversations, lack of insight Anterograde Amnesia - Inability to form new memories Retrograde Amnesia - Inability to recall memories prior to an event Confabulation - Creating false memories or distorting real memories Apathy - Lack of emotion Sensory memory - Memory of stimuli after stimuli is removed; lasts less than a second Short-term memory - Temporary immediate recall of information for processing; lasts less than a minute Chunking - Combining items into groups Working Memory - Ability to manipulate mental information Explicit Memory - Information consciously remembered Implicit Memory - Information unconsciously remembered Procedural Memory - Action-based information: processes, working memory, etc Declarative Memory - Intentionally recalled information Episodic Memory - Information based in experiences Semantic Memory - Facts, figures, dates, etc Long-term Memory - Stored memory Broca's Aphasia - Partial or total loss of ability to produce language Wernicke's Aphasia - Inability to understand language Aphasia - Loss of ability to comprehend or formulate language; different from a developmental delay or dysfunction Joint Attention - Two or more people paying attention to the same object Theory of Mind - Recognition that others have a different perspective of same events Parietal Lobe - Part of the brain responsible for somatosensory processing Frontal Lobe - Mediates planning and necessary functions of planning Occipital Lobe - Processing and storing visual information Temporal Lobe - Processing and storing auditory information Limbic System - Part of the brain responsible for emotions and memory processing Cerebellum - Part of the brain responsible for motor coordination Brain Stem - Responsible for basic life functions Cerebrum - Outer most layer of the brain; contains the cortex and its connecting axons; also known as the telencephalon Corpus Callosum - Connects the left and right hemispheres of the brain Amygdala - Responsible for emotional memory, specifically fear based memories Thalamus - Relay station of the brain Hippocampus - Responsible for storing memories from short-term to long-term and responsible for spatial memory Hypothalamus - Regulates secretion of hormones Basal Ganglia - Part of the brain responsible for regulating voluntary movement
