Week 1 - Perspectives on the Brain, Mind and Mental Health Flashcards
In what most basic way might you define what the brain is?
An organ of the human body
What is an organ in the biological sense?
A structure of the body that serves a particular function, such as the lungs or heart
What is the definition of a biological system?
A group of interrelated organs and tissues that work together to serve a particular function
What are the constituent parts of the nervous system?
- Brain
- Spinal cord
- All of the peripheral nerves of the body
What are neurons?
Brain cells that relay messages within and between brain areas, and from the brain to the rest of the body and back
What are the five different types of neuron?
- Multipolar neuron
- Pyramidal neuron
- Purkinje cell
- Bipolar neuron
- Unipolar neuron
What is the main similarity between the different types of neuron?
They all have a cell body and lots of branching dendrites
What are glial cells?
Cells that play a supporting and protective role within the brain
What function do glial cells perform?
They clear away waste, such as dead neurons
What is meant by the term plasticity?
The ability of the brain to adapt and change as a result of experience
What does the field of cognitive neuroscience investigate?
The ‘thinking’ functions, and the processes within the brain that support these
What does the field of neuroanatomy investigate?
The structure and organisation of the brain
How would a cognitive neuroscientist study the brain?
They would monitor living participants using a variety of technical equipment, such as fMRIs
How would a neuroanatomist study the brain?
They would study the brain postmortem using techniques such as slicing and staining to make features of the brain tissue more easily visible
What does the field of neurogenetics investigate?
The genetics which underpin the nervous system
What does the term translational research mean?
Reserarch which is conducted in a laboratory setting and can be carried across to have a clinical impact
What is meant by the term mental state?
Mental activities which include thinking, beliving and feeling
What viewpoint regarding the brain did the French philosopher Rene Descartes propose?
That the body and mind are different entitities - the brain is physical, whereas the mind takes on a more ethereal form
What approach to the mind did the American philosopher John Searle propose?
That minds and bodies are not different entitiies, and that mental states are an intrinsic property of complex biological systems - that you could not have mental states without a functioning brain
What may be a problem with John Searle’s approach to the mind?
His proposition would mean that when the brain dies, the mind dies with it, which could raise ethical questions about when the mind begins and ends
