Question 1

What is the brain?

Answer 1

the brain is a physical object, a living tissue and a body organ.

Question 2

What is behaviour?

Answer 2

Behaviour is action, it is momentarily observable but fleeting.
behaviour and the brain evolved together and each one causes the other to be the way it is.

Question 3

What cells are the brain made out of?

Answer 3

half of the cells are neurons and the other have are filial cells which support the function of neurons.

Question 4

What is the central nervous system(CNS)?

Answer 4

The central nervous system is made up of both the brain and the spinal cord.
-most connections between the brain and the rest of the body are made through the spinal cord.

Question 5

What is the input and output of the spinal cord?

Answer 5

-The output is nerve fibres from the spinal cord to the muscles and organs.
-the input is sensory receptors sending signals into the spinal cord.

Question 6

What is the peripheral nervous system?

Answer 6

it is all of the neurones in the body outside of the brain and spinal cord.
-sensory and motor connections

Question 7

What is the cerebellum?

Answer 7

-The cerebellum is the main forebrain structure and it has two nearly identical hemispheres
-cerebellums are more prominent in mammals and birds.
-responsible for most conscious behaviour.

Question 8

What is the brainstem?

Answer 8

it is a set of structures responsible for critical unconscious behaviour such as breathing.

Question 9

what Is the brain?

Answer 9

refers to an intelligent functioning organ that is connected to the rest of the nervous system and body to produce behaviour.

Question 10

What is Psyche?

Answer 10

it is a nonmaterial entity that governs our behaviour, and our essential consciousness survives our death.

Question 11

What is meantalisim?

Answer 11

A persons mind (psyche) controls behaviour.
-Aristotle

Question 12

What is dualism?

Answer 12

-the mind receives information from the body through the brain.

wether or not mental phenomenon are a subset of physical phenomena or not.

Question 14

What is materialism?

Answer 16

Philosophical position where behaviour is explained as a function of the body without the mind.
-darwin

Question 17

Gregor Medel

Answer 17

-Genes over various physical traits displayed by the species
-members of a species with the same genotype will likely end up showing similar phenotypic traits.
-

Question 18

What are epigenetics?

Answer 18

-the study of differences in gene expression arising from environment and experience.
-epeginetic factors influence how genes express the traits inherited from the parents
-epegenetic changes can persist through a lifetime.
