Central and peripheral nervous system. Central and peripheral nervous system. Anatomy and function. Signal transmission in the neuron- action potential and the synapse. Neurotransmitters- types and function in health and disease.

Central Nervous System (CNS) and Peripheral Nervous Systems (PNS) Structure

Central Nervous System (CNS) and Peripheral Nervous Systems (PNS)

Neural basis of sensation Sensory information is transduced by receptors

The visual system- Sensory transduction

Neural basis of sensation Sensory information is transduced by receptors Pathways: The information travels from receptors to ganglion cells to the thalamus- the entry gate to the cortex

Topographical arrangement in the cortex

The somatosensory “homunculus”

The central nervous system

H.M. – a case of Anterograde amnesia The hippocampus and parahippocampal region of H.M were removed Anterograde amnesia These areas are crucial for formation and consolidation of long-term memories about facts and events

Action potential

Neuronal networks - summary

Neurotransmitters and Neuromodulators Modulators of brain function. Types. Researchers learn about their function from disease and drug function.

Neurotransmitters – Amino Acids

Neurotransmitters – Acetylcholine (Ach)

Neurotransmitters - Dopamine

Neurotransmitters – others Serotonin Peptides Trophic factors Hormones Gases Lipid messengers
