Nervous System
This part of the nervous system includes the brain and spinal cord.
What is the central nervous system (CNS)?
This part of the hindbrain controls vital functions like heart rate and breathing
What is the medulla?
This man survived a severe brain injury in 1848, providing early evidence of brain localisation.
Who is Phineas Gage?
This method records electrical activity in the brain and is often used to study sleep.
What is an electroencephalogram (EEG)?
This part of the neuron contains the nucleus and is responsible for maintaining the cell.
What is the soma (cell body)?
This division of the peripheral nervous system controls voluntary movements.
What is the somatic nervous system?
This part of the midbrain is involved in arousal and alertness.
What is the reticular formation?
This area of Phineas Gage's brain was damaged, leading to changes in his personality.
What is the frontal lobe?
This imaging technique uses X-rays to create detailed images of the brain's structure
What is computed tomography (CT)?
This part of the neuron transmits electrical impulses away from the cell body.
What is the axon?
This part of the autonomic nervous system is responsible for the 'fight or flight' response.
What is the sympathetic nervous system?
This part of the forebrain regulates body temperature, hunger, and thirst.
What is the hypothalamus?
This researcher conducted split-brain experiments to study the role of the corpus callosum.
Who is Roger Sperry?
This method uses magnetic fields and radio waves to produce detailed images of the brain.
What is magnetic resonance imaging (MRI)?
These chemicals transmit signals across the synapse from one neuron to another.
What are neurotransmitters?
These nerves carry information from sensory receptors to the central nervous system.
What are sensory nerves?
This structure connects the left and right hemispheres of the brain.
What is the corpus callosum?
This procedure involved severing connections in the prefrontal cortex and was performed by Walter Freeman.
What is a frontal lobotomy?
This imaging technique measures brain activity by detecting changes in blood flow.
What is functional magnetic resonance imaging (fMRI)?
This type of neuron carries signals from the central nervous system to muscles and glands.
What are motor neurons?
This part of a neuron receives signals from other neurons.
What are dendrites?
This lobe of the brain is responsible for processing visual information.
What is the occipital lobe?
These ethical concerns arose from Walter Freeman's frontal lobotomies.
What are the lack of informed consent and the protection from harm of the procedure?
This is a limitation of using EEGs to study brain function.
What is the poor spatial resolution? (precise location of neural activity)
This term describes the process by which neural impulses are transmitted from the dendrites to the axon terminal and across the synapse.
What is the electrochemical nature of neural impulses?
