Early Brain Investigation
This practice involved examining the shape of the skull to supposedly determine personality and mental abilities.
What is phrenology?
This technique records electrical activity produced by the brain using electrodes placed on the scalp.
What is EEG?
These structures receive signals from other neurons.
What are dendrites?
The brain can be broadly divided into these three major areas.
What are the hindbrain, midbrain and forebrain?
The nervous system is divided into these two major divisions.
What are the central nervous system and peripheral nervous system?
This researcher is associated with the development of phrenology.
Who is Franz Gall?
This technique produces detailed structural images of the brain using magnetic fields and radio waves.
What is MRI?
This long structure carries neural impulses away from the cell body.
What is the axon?
This brain region is primarily associated with the production of speech.
What is Broca’s area?
The brain and spinal cord make up this division.
What is the central nervous system (CNS)?
What is Topic 1 called?
What is the role of the brain.
This technique measures changes in brain activity by detecting changes in blood oxygenation.
What is fMRI?
This fatty insulating layer surrounds many axons and increases the speed of neural transmission.
What is the myelin sheath?
This brain region is primarily associated with understanding language.
What is Wernicke’s area?
All nerves outside the brain and spinal cord make up this division.
What is the peripheral nervous system (PNS)?
This researcher conducted experimental neurosurgery on animals and challenged the idea that specific brain functions were strictly localised.
Who is Pierre Flourens?
This technique uses a radioactive tracer to show metabolic activity and glucose levels in different areas of the brain.
What is PET?
A neuron receives information from another neuron, processes it and passes information to a muscle. Identify the three neuron types that could be involved.
What are sensory neurons, interneurons and motor neurons?
This region connects information between Wernicke’s area and Broca’s area and contributes to language processing.
What is Geschwind’s territory?
The peripheral nervous system can be divided into these two systems.
What are the somatic nervous system and autonomic nervous system?
Why is early brain research considered a Science as a Human Endeavour issue?
Because some knowledge was obtained through risky, invasive or ethically questionable procedures, raising questions about the costs and ethics of scientific progress.
What methos are used to enhance the understanding of the structure of the brain and its relationship to cognition, emotion and behaviour
What are neuroimaging techniques
A person suddenly encounters a dangerous animal and their heart rate increases automatically. Which division is primarily responsible?
What is the autonomic nervous system?
Damage to Broca’s area would most likely cause difficulties with this aspect of language.
What is producing fluent speech?
The autonomic nervous system controls functions that generally occur without conscious control, such as heart rate and digestion. What does the somatic nervous system primarily control?
What is voluntary movement of skeletal muscles?
