The Nervous Systems

❌- made up of the brain and spinal cord. The spinal cord is responsible for reflex actions, while the brain is the centre of all conscious awareness. It has a very advanced cerebral cortex compared to animals.
❌- made up of millions of neurons that transmit messages to and from the CNS.
❌- a subsystem of the PNS, this nervous system controls bodily functions, like breathing and heart rate
❌- a subsystem of the PNS, this nervous system controls voluntary movement.
❌- a branch of the ANS which is involved in the fight or flight response, and makes the body physiologically aroused
❌- a branch of the ANS which is involved in the fight or flight response, and returns the body to its resting state.

There are three types of evidence which support localisation of function:

Brain scan evidence: ( Peterson, Wernicke, Tulving, Baddeley ) did brain scans and found Wernicke's area was active during listening tasks (understanding speech), while Broca's area was active for reading aloud tasks (speech production). ( Tulving, Peterson, Wernicke, Baddeley ) found that episodic and semantic memories were stored on different sides of the pre-frontal lobe. This type of evidence is scientific and objective.
Neurosurgical evidence: ( Dougherty, Baddeley, Tulving, Wernicke ) suggested that lesioning the cingulate gyrus helps treat OCD
Case study evidence: ( Phineas Gage, Clive Wearing, KF, Little Albert ) had a pole through his head which damaged the frontal lobe, and he became rash and lacked restraint. This shows the function of the frontal lobe

Explicación

Pregunta 17 de 67

There are two main disadvantages of the localisation of function theory:
❌'s research: he removed parts of the cortex in rats and found that it didn't matter which part was removed, the effect on learning was the same. This supports the holistic view.
❌: when damaged, the brain can reorganise itself to recover the lost function. This suggests that all parts of the brain are involved in functions, thus supporting the holistic theory.
