  • What are the two main divisions of the nervous system?
    Central Nervous System (CNS) and Peripheral Nervous System (PNS)
  • What does the Central Nervous System (CNS) consist of?
    The brain and spinal cord
  • What is the function of the Central Nervous System (CNS)?
    It processes information and sends out instructions
  • What does the Peripheral Nervous System (PNS) split into?
    Somatic Nervous System (SNS) and Autonomic Nervous System (ANS)
  • What is the role of the Autonomic Nervous System (ANS)?
    It manages tasks without conscious control
  • What are the three types of neurons?
    Sensory, Relay, and Motor neurons
  • What is the function of sensory neurons?
    They collect information from our senses
  • What do relay neurons do?
    Process and transmit information within the CNS
  • What is the function of motor neurons?
    They carry signals to muscles and glands
  • How does synaptic transmission work?
    It involves neuron communication via neurotransmitters
  • What are neurotransmitters?
    Messengers that carry signals between neurons
  • What happens when caffeine blocks adenosine?
    Increased alertness and reduced sleepiness
  • What is excitement in synaptic transmission?
    It activates a neuron, making it eager
  • What is inhibition in synaptic transmission?
    It slows down a neuron, reducing activity
  • What is the function of the endocrine system?
    It uses hormones to control body functions
  • How does the endocrine system work with the nervous system?
    It provides slower, long-lasting instructions
  • What do glands do in the endocrine system?
    Produce hormones and release them into the bloodstream
  • What is the fight or flight response?
    Body's reaction to perceived threat or danger
  • What role does adrenaline play in the fight or flight response?
    Boosts heart rate and alertness for action
  • What does the motor cortex control?
    Voluntary muscle movements
  • What does the somatosensory cortex process?
    Sensory information like touch and temperature
  • What is the function of the visual cortex?
    Processes visual information for understanding
  • What does the auditory cortex handle?
    Sound processing, including speech and music
  • What is Broca's area linked to?
    Speech production
  • What happens if Broca's area is damaged?
    Difficulty forming words and sentences
  • What is Wernicke's area involved in?
    Language comprehension
  • What happens if Wernicke's area is damaged?
    Fluent but nonsensical speech
  • What happened in the case of Phineas Gage?
    His personality changed after a brain injury
  • What does hemispheric lateralisation refer to?
    Specialised functions of each brain hemisphere
  • What is the left hemisphere associated with?
    Language and logical reasoning
  • What is the right hemisphere linked to?
    Creativity and spatial awareness
  • What did Roger Sperry's split brain research reveal?
    Each hemisphere processes information independently
  • What limitation exists in split brain studies?
    Small participant groups limit generalisability
  • What is plasticity in the brain?
    Brain's ability to adapt after injury
  • What are the two types of brain plasticity?
    Structural and Functional Plasticity
  • What is structural plasticity?
    Growth of new neurons and synaptic connections
  • What is functional plasticity?
    Redistribution of functions from damaged areas
  • What did Maguire et al. (2000) study?
    London taxi drivers' hippocampi size
  • What did Maguire et al. (2000) find about taxi drivers?
    They had larger hippocampi than control subjects
  • What is a limitation of brain plasticity?
    Plasticity declines with age
