Biological approach definitions

What is the biological approach?

The biological approach studies how biological factors such as brain structure, neurotransmitters, hormones, and genetics influence behaviour.

What is localisation of function?

Localisation of function is the idea that specific areas of the brain are responsible for specific behaviours or cognitive processes.

What is neuroplasticity?

Neuroplasticity is the brain’s ability to reorganise and form new neural connections throughout life, especially after learning or injury.

What is a neuron?

A neuron is a nerve cell that transmits electrical and chemical signals in the brain and nervous system.

What is a neurotransmitter?

A neurotransmitter is a chemical messenger that transmits signals across synapses between neurons.

What is synaptic transmission?

Synaptic transmission is the process by which neurotransmitters are released by one neuron and bind to receptors on another, transmitting a signal.

What is a hormone?

A hormone is a chemical substance released by glands in the endocrine system that affects behaviour and physiology.

What is the endocrine system?

The endocrine system is a collection of glands that release hormones into the bloodstream to regulate body functions and behaviour.

What are pheromones?

Pheromones are chemical substances released by animals (including humans) that affect the behaviour or physiology of others of the same species.

What is an MRI?

MRI (Magnetic Resonance Imaging) is a technique that uses magnetic fields and radio waves to create detailed images of brain structure.

What is an fMRI?

fMRI (Functional Magnetic Resonance Imaging) measures brain activity by detecting changes in blood flow.

What is genetic inheritance?

Genetic inheritance is the passing of genetic information from parents to offspring, influencing traits and behaviour.

What is a gene?

A gene is a segment of DNA that carries instructions for the development of traits and behaviours.

What is epigenetics?

Epigenetics is the study of how environmental factors can change gene expression without altering the DNA sequence.

What is a twin study?

A twin study compares the behaviour of identical and fraternal twins to estimate the relative influence of genetics and environment.
