9 important questions on Appendix - neuroscience

What brain area where physicians interested in by the early nineteenth century?

The cerebral cortex

What did Franz Joseph Gall discover about the cerebral cortex and what study field is associated with him?

He thought that the size of the cerebral cortex changed behaviour. Thus he thought that you could feel the brain size on the scalp and know how someone's personality is. This is called phrenology

What is the name we use for phrenology in more recent years

Localisation of function
  • Higher grades + faster learning
  • Never study anything twice
  • 100% sure, 100% understanding
Discover Study Smart

Who and when discovered Neurons?

Santiago Ramon Y Cajal before the turn of the twentieth century.

What did the discovery of neurons imply?

It implies that cognitive processes are carried out by large populations of neurons

Signals that are transmitted long distance alone neuronal axons are called

Action potentials

What are the chemical substances that neurons use to stimulate the cells they contact?

Neurotransmitters

How did William Penfield create a systematic map of the somatosensory cortex?

By running an electric current through the exposed cerebral cortex of the patient. By changing location and monitoring behaviour the map was made

How are neurological conditions neuroscientificly different from psychiatric disorders?

Neurological conditions are more cellular problems
psychiatric disorders arise from neurotransmitter dysfunctions

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
Remember faster, study better. Scientifically proven.
