1. Biopsychology

1.1. Nervous System

1.1.1. AO1 Collect, process and respond to info from environment coordinate bodily function Central Nervous System Brain Spinal Cord Peripheral Nervous System Autonomic Nervous System Somatic Nervous System

1.2. Synaptic Transmission

1.2.1. AO1 Neurons soma, axon, dendrites, axon terminals, myelin sheath negatively charged action potential Motor Neuron Relay Neuron Sensory Neuron Synapse action potential reaches end of post synaptic cell excites vesicles to bind with membrance releases neurotransmitters into synapse binds with receptor sites several dozen NTs each fits like lock and key with specific function some inhibitory some excitatory

1.3. Endocrine System

1.3.1. AO1 slow but widespread and powerful glands, hormones, bloodstream pituitary brain master adrenal Hypothalamus Noradrenaline - trigger sympathetic Adrenal medulla - adrenal gland dilate pupils, increase breathing.. reproductive testes/ovary testosterone/oestrogen puberty changes pineal brain melotonin sleep

1.7. Ways of Studying the Brain

1.7.1. fMRI AO1 blood oxygenation 3d activation map AO3 no radiation high spatial resolution expensive poor temporal resolution

1.7.2. EEG AO1 electrical activity skull cap overall brain wave diagnose arrhythmic patterns AO3 good diagnostic tool good stages of sleep high temporal resolution very poor spatial resolution

1.7.3. ERP AO1 EEg technology baseline test specific stimuli AO3 Good temporal (like EEG) not easy to get rid of extraneous noise

1.7.4. Post Mortem AO1 dead brain good for rare disorders compare to typical brain HM AO3 vital in early days vital for medical knowledge Causation Consent

1.8. Circadian

1.9. Exogenous & Endogenous

1.9.1. AO1 Endo SCN Animal Studies Pineal Gland Exo Entrainment Light (knees) Social (babies)

1.9.2. AO3 over simplified (more than master clock) Overstated effects of exo Method issues Interactionism

1.10. Infradian & Ultradian

1.10.1. AO1 Infradian Greater than 24hr (the cycle is longer than 24hrs) Menstrual SAD Ultradian less than 24hr (the cycle is shorter than 24hrs) Sleep Stages 90mins Stage 1-2 Stage 3-4 Stage 5

1.10.2. AO3 Evolutionary basis of menstrual cycle Method issues Supporting evidence for sleep stages Animal studies Practical Application - SAD
