Study Notes
Nervous System
- The nervous system consists of:
- Central Nervous System (CNS): brain and spinal cord
- Peripheral Nervous System (PNS): nerves that connect CNS to the rest of the body
- Functions:
- Integration and processing of information
- Control of voluntary and involuntary movements
- Regulation of body functions (e.g. heart rate, blood pressure)
Neurons
- Basic units of the nervous system
- Consist of:
- Dendrites: receive signals
- Cell body: processes information
- Axon: transmits signals
- Terminal buttons: release neurotransmitters
- Types of neurons:
- Sensory neurons: transmit information from senses to CNS
- Motor neurons: transmit information from CNS to muscles and glands
- Interneurons: integrate and process information within the CNS
Neurotransmission
- Process by which neurons communicate with each other
- Steps:
- Synthesis: neurotransmitters are produced in the terminal buttons
- Storage: neurotransmitters are stored in vesicles
- Release: neurotransmitters are released into the synapse
- Binding: neurotransmitters bind to receptors on the postsynaptic neuron
- Signal transmission: signal is transmitted to the postsynaptic neuron
- Termination: signal is terminated through reuptake or breakdown of neurotransmitters
Neurotransmitters
- Chemical messengers that transmit signals between neurons
- Examples:
- Acetylcholine: involved in muscle contraction, memory, and learning
- Dopamine: involved in motivation, reward, and movement
- Serotonin: involved in mood regulation, appetite, and sleep
- Norepinephrine: involved in attention, arousal, and stress response
Brain Structures
- Cerebrum: divided into two hemispheres, responsible for higher-level thinking and processing
- Cerebellum: coordinates movement and balance
- Brainstem: regulates basic functions such as breathing, heart rate, and blood pressure
- Limbic system: involved in emotions, motivation, and memory
- Hippocampus: plays a key role in forming and consolidating new memories
Genetics and Behaviour
- Genes influence behaviour through the expression of proteins and neurotransmitters
- Epigenetics: environmental factors can influence gene expression
- Heritability: the proportion of variation in a behaviour that can be attributed to genetics
- Gene-environment interaction: the interaction between genetic and environmental factors that influences behaviour
Nervous System
- Consists of Central Nervous System (CNS) and Peripheral Nervous System (PNS)
- CNS includes brain and spinal cord, while PNS includes nerves that connect CNS to the rest of the body
- Functions include integration and processing of information, control of voluntary and involuntary movements, and regulation of body functions like heart rate and blood pressure
Neurons
- Basic units of the nervous system, consisting of dendrites, cell body, axon, and terminal buttons
- Dendrites receive signals, cell body processes information, axon transmits signals, and terminal buttons release neurotransmitters
- Types of neurons include sensory neurons, motor neurons, and interneurons
- Sensory neurons transmit information from senses to CNS, motor neurons transmit information from CNS to muscles and glands, and interneurons integrate and process information within the CNS
Neurotransmission
- Process by which neurons communicate with each other through neurotransmitters
- Neurotransmitters are synthesized in terminal buttons, stored in vesicles, released into the synapse, bind to receptors on the postsynaptic neuron, and transmit signals
- Signal transmission is terminated through reuptake or breakdown of neurotransmitters
Neurotransmitters
- Chemical messengers that transmit signals between neurons
- Examples include acetylcholine, dopamine, serotonin, and norepinephrine
