❌- 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.

❌: the auditory area in which speech-based information is analysed. It is also in charge of facial recognition. Damage leads to partial hearing loss
❌: controls understanding speech. Damage leads to Wernicke's aphasia (fluent but nonsensical speech)
❌: controls speech production. Damage leads to Broca's aphasia (non-fluent and labourious speech)

Selecione das listas do Menu para completar o texto.

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

Explicação

Questão 17 de 67

1

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.
