Biology and Behavior Flashcards
Neuropsychology
The study of the connection between the nervous system and behavior. Focuses on functions of brain regions
Three types of neurons in the Nervous System
Sensory, motor and interneurons
Another name for sensory neurons
Afferent
Another name for motor neurons
Efferent
Reflex Arcs
System that relays information to the source of stimuli while routing it simultaneously to the brain
Uses the spinal cord
2 Parts of Nervous System
CNS & PNS
2 Parts of CNS
Brain and Spinal Cord
Components of PNS
Spinal nerves
2 Divisions of PNS
Somatic and Autonomic NS
2 Divisions of Autonomic NS
Sympathetic & Parasympathetic
3 Divisions of Brain (anatomically)
Hind, mid and forebrain
Parts of Hindbrain
Cerebellum, Medulla oblongata and reticular formation
Parts of Midbrain
Inferior and Superior Colliculi
Parts of Forebrain
Cerebral cortex, Hypothalamus, Thalamus, Basal Ganglia, Limbic System
Methods for Studying the Brain
- Lesions
- stimulation and activity measurement using EEG
- Regional Cerebral Blood flow
Function of Thalamus
Relay Station for Sensory Information
Function of Hypothalamus
Structure connected to the anterior pituitary and endocrine system through the hypophyseal portal system Maintains homeostasis (T, metabolism)
Function of Basal Ganglia
Smoothens movements and maintains postural stability
Components of Limbic System
Septal Nuclei, amygdala, and hippocampus
Function of the Limbic System
Controls emotion and memory
Function of Septal Nuclei
Involved in feeling of pleasure, pleasure seeking behavior and addiction
Function of Amygdala
Controls fear and aggression
Hippocampus
Aggregates memory and communicates with other parts of the limbic system through an extension known as fornix
4 Parts of Cerebral Cortex
Frontal, Parietal, Occipital, Temporal
Functions of the Frontal Lobe
Responsible for executive functions, long-term planning, impulse control, speech production, motor function
Function of the Parietal Lobe
Controls
- Sensation of touch, temperature, pressure, pain
- spatial processing, orientation and manipulation
Function of the Occipital Lobe
Controls visual processing
Functions of the Temporal Lobe
Controls
- memory and emotion
- Sound processing and speech perception
