Study Notes
Biological Psychology
- Studies the connection between biological processes and behaviors, emotions, and cognition.
- Key Focus Areas:
- Brain structures (e.g., amygdala, hippocampus)
- Nervous system (CNS & PNS)
- Endocrine system
- Neurotransmitters and hormones
Neurons
- Basic units of the nervous system
- Transmit electrical and chemical signals
- Composed of dendrites, axon, and cell body
Neurotransmitters
- Chemicals that transmit signals across synapses
- Examples: dopamine, serotonin, acetylcholine
Synaptic Transmission
- The process by which neurotransmitters are released by one neuron, cross the synapse, and bind to receptors on another neuron.
Brain Structures
- Amygdala: Regulates emotions and stress responses
- Hippocampus: Involved in memory and learning
- Lobes: Frontal, parietal, temporal, occipital
Nervous System Divisions
- CNS: Brain and spinal cord
- PNS: Somatic (voluntary control) and autonomic (involuntary functions)
Autonomic Nervous System
- Sympathetic Division: Prepares body for "fight or flight"
- Parasympathetic Division: Supports "rest and digest" functions
Endocrine System
- Glands that release hormones
- Influences mood, metabolism, growth, and sexual development
Importance of Biological Psychology
- Helps understand how biological factors influence behaviors
- Provides insights into mental health conditions (e.g., depression, anxiety)
Biological Psychology vs. Physiological Psychology
- Biological Psychology examines how physiological processes relate to psychological phenomena
- Physiological Psychology investigates how different brain regions control various behaviors and mental processes
Classify the Nervous System Structurally
- Central Nervous System (CNS): Brain and spinal cord
- Peripheral Nervous System (PNS): Cranial nerves, Spinal nerves
General Features of a Neuron
- Vary in size and shape
- Share certain features: Dendrites, A cell body, An axon
Central Nervous System (CNS)
- Brain and spinal cord
- Receives sensory input, integrates information, directs motor responses
Brain
- Controls sensory perception, thoughts, emotions, and behaviors
- Composed of lobes: Frontal, parietal, temporal, occipital
The Spinal Cord
- Slender column of nervous tissue continuous with brain and brainstem
- Extends downward through vertebral canal
- Begins at the foramen magnum and terminates at the first and second lumbar vertebrae (L1/L2) interspace
Peripheral Nervous System (PNS)
- Nerves and ganglia outside the brain and spinal cord.
- Brain contains 12 pairs of cranial nerves
- Spinal cord contains 31 pairs of peripheral nerves
Autonomic Nervous System
- Functions without conscious effort
- Controls visceral activities
- Regulates smooth muscle, cardiac muscle, and glands
- Two divisions:
- Sympathetic Division: Speeds up bodily processes (fight or flight)
- Parasympathetic Division: Slows down bodily processes (rest and digest)
