Chapter 3 Flashcards
Biological Psychology
Link between Biology and behavior
Evolutionary Psychology
Evolution of behavior
Nervous System
Central and Peripheral
Neuron
Building block of the nervous system
Dendrites
Receive information form other neurons
Synapse
Gap that separates axon form dendrite
Serotonin
Regulates mood, arousal, hunger and sleep
Dopamine
Movement, Learning, Attention, Emotion
Drugs
Affect neurotransmitters
Neuron Death
Trauma, Abuse, Wear and Tear
Central Nervous System (CNS)
Brain and Spinal Cord
Peripheral Nervous System (PNS)
Somatic and Autonomic
Autonomic Nervous System (ANS)
Sympathetic and Parasympathetic
Sympathetic Nervous System
Arousal, Flight or Fight
Parasympathetic Nervous System
Calming, Rest and digest
Somatic Nervous System (SNS)
Motor output and Sensory Input
Biofeedback
Blood pressure, muscle tension
Neurofeedback
Brain waves
Nerves
Collection of neurons
Brain
Hindbrain, Midbrain, Forebrain
Hindbrain
Medulla, Pons, Cerebellum, Reticular formation
Reticular formation
Arousal, Sleep, Walking, Conscoiusness
Medulla
Heart-Rate and Breathing
Pons
Automatic and unconscious movements
Cerebellum
Balance, Coordination, Voluntary movement
Midbrain
Coordinates signals from hindbrain and forebrain
Forebrain
Limbic system and Cerebral cortex
Limbic System
Emotion and Motivation. Hypothalamus, Amygdala, Hippocampus
Cerebral Cortex
Cognition, Language, Thinking, Memory, Abstract reasoning, Speech
Hypothalamus
Feeding, Fighting, Fleeing, Mating
Amygdala
Aggression, Fear, Emotion laden memories
Hippocampus
Memory formation, indexing
Infantile Amnesia
Inability to remember info before age 3
Parietal Lobe
Body sensations, pressure pain, temperature, touch
Temporal Lobe
Hearing, language comprehension, face recognition
Occipital Lobe
Vision and visual perception
Frontal Lobe
Speaking, muscle movement, planning, judgment, impulse control
Corpus Callosum
Connects right and left hemispheres
Left hemisphere
Controls right side, speech, language, writing, logic
Right hemisphere
Controls left side, Spatial Skills, Creative thinking, Fantasy thinking, Artistic and music ability
Motor cortex
In frontal lobe, voluntary movement
Somatosensory cortex
In parietal lobe, registers sensations
Auditory cortex
In temporal lobe, auditory information
Receiving stations
Sensory information
Dispatch stations
Motor commands
Visual cortex
In occipital lobe, visual information
Endocrine system
Secretes Hormones into bloodstream
Hormones
testosterone, estrogen, affect tissue
Hypothalamic-Pituitary-Adrenal (HPA)
In the name, secrets hormones
