Q

What is classical conditioning?

A

Learning by association that occurs when two stimuli are repeatedly paired together (an unconditioned stimulus and a neutral stimulus). The neutral stimulus eventually produces the same response that was produced by the unconditioned stimulus alone.

A

Transmitted information from receptor cells in the sense organs to the CNS. It also receives information from the CNS that directs muscles to act.

58
Q

59
Q

What is the endocrine system?

A

One of the body’s major information systems that instructs glands to release hormones directly into the bloodstream. These hormones are carried towards target organs in the body.

60
Q

What is a gland?

A

An organ in the body that synthesizes substances such as hormones.

61
Q

What are hormones?

A

Chemical substances that circulate in the bloodstream and only affect target organs. They are produced in large quantities but disappear quickly.

62
Q

What is the fight or flight response?

A

They wan an animal responds when stressed. The body becomes physiologically aroused in readiness to fight an aggressor and flee.

63
Q

What is adrenaline?

A

A hormone produced by the adrenal glands which is part of the human body’s immediate stress repose system. Adrenaline has a strong effect now the cells of the cardiovascular system- stimulating the heart rate, contracting blood vessels and dilating air passages.

64
Q

What is a neuron?

A

The basic building blocks of the nervous system, neurons are nerve cells that process and transmit messages through the electrical and chemical signals.

65
Q

What is a sensory neuron?

A

These carry messages from the PNS to the CNS. They have long dendrites and short axons.

66
Q

What is the relay neuron?

A

These connect the sensory neurons to the motor or other relay neurons. They have short dendrites and short axons.

67
Q

What are motor neurons?

A

These connect the CNS to effectors such as muscles and glands, they have short dendrites and long axons.

68
Q

What is action potential?

A

When a neuron is activated by a stimulus, the inside of the cell becomes positively charged for a split second causing action potential.

69
Q

What is synaptic transmission?

A

The process by which neighboring neurons communicate with each other by sending chemical messages across the gap that separates them.

70
Q

What are neurotransmitters?

A

Brain chemicals released from synaptic vesicles that relay signals across the synapse from one neuron to another. Neurotransmitters can be broadly divided into those that perform an excitatory function and those that perform an inhibitory function.

71
Q

What is excitation?

A

When a neurotransmitter wish as adrenalin increases the positive charge of the postsynaptic neuron.

72
Q

What is inhibition?

82
Q

What is functional recovery?

A

A form of plasticity, the brains ability to redistribute or transfer functions: following damage through trauma.

83
Q

What is synaptic pruning?

A

As we age, rarely used connections are deleted and frequently used connections are strengthened.

84
Q

What is Axonal sprouting?

A

I damaged axons grow nerve endings to reconnect neurone whose links were injured or severed.

85
Q

What is the recruitment of homologous areas?

A

Regions on opposite sides of the brain take on functions of damaged areas.

86
Q

Evaluate brain plasticity and recovery?

A
  • helps in the treatment of patients with previous illnesses or degenerative diseases
  • bad effects, drugs can have irreparable effects on the brain
  • this has helped the brain processes of aging old people with degenerative diseases
  • a kitten with an eye sewed shut had the previously active area of brain taking on other functions
  • the use of the brain determines how active and well the brain will be later

How we’re split brain research carried out?

A

Image/word is projected to right visual field or left

90
Q

What did split research find?

A

Pictures shown to the RVF could be described but not to the LVF because there is no language centres in the left hemisphere connected to the RVF.
And they could not describe objects projected to the LVF, but also to select a matching ob next with left hand.
