Study Notes
Biological Basis of Behavior
- Neurons have dendrites, axons, and synaptic terminals.
- Synaptic communication is the process of communication between neurons.
- Action potentials involve ion movement (depolarization), maintaining resting potential (sodium-potassium pump), and reaching a threshold.
- GABA is inhibitory, glutamate is excitatory.
- Central nervous system (CNS) vs peripheral nervous system (PNS).
- Brain lobes and functions (e.g., language areas).
- Corpus callosum's role in split-brain patients.
- Limbic system structures and functions (amygdala, hippocampus).
- Thalamus's role.
- Hypothalamus and pituitary gland.
- Hindbrain (cerebellum, pons, medulla, reticular formation).
- Midbrain structures and functions.
Sensation and Perception
- Sensation versus perception.
- Transduction: converting energy into neural signals.
- Types of sensory cells (e.g., cones and rods in the eye).
- Senses and the type of energy they transduce (e.g., soundwaves in hearing).
- Visual system: eye structure and visual perception (excluding action potential generation).
- Hyperpolarization (exception to synaptic transduction, do not need to know the whole process).
- Bottom-up vs top-down processing.
- Gestalt principles of perception.
- Olfactory system: receptors for smells and connection to the limbic system.
Memory and Attention
- Memory processing (encoding, consolidating, retrieving).
- Long-term potentiation (LTP) and sleep's role in consolidation.
- Amygdala function.
- Hippocampus function.
Abnormal Psychology
- Symptoms of disorders (OCD, anxiety, depression, schizophrenia).
- Differentiating between specific phobia and generalized anxiety disorder (GAD).
- Biological theories for disorders (e.g., serotonin in depression).
- Unipolar vs Bipolar disorders
- Schizophrenia: positive vs negative symptoms
- Common therapy factors.
- Trauma and Resilience
- HPA-Axis
- Role of the Amygdala, Hippocampus, and Prefrontal Cortex (PPC) and Posterior Cingulate Cortex (PCC).
- Definition of trauma (DSM criteria).
- PTSD definition.
- PTSD major symptoms
- Brain networks.
- PTSD: hyperactive amygdala, reduced hippocampal volume (predisposition factor).
- Epigenetics.
- Methylation as a biological process.
Evolutionary Psychology (Relevant to PSY102-6X section only)
- Evolution and natural selection vs sexual selection.
- K-species vs R-species
- Intrasexual and intersexual competition
- Hamilton's Rule of relatedness
- Individual selection vs kin selection vs. reciprocal altruism
- Parental investment, pair-bonding, vs. tournament-species
- Biological purpose of emotions.
- Trade-offs in biological systems.
- Mating strategies in humans.
