Exploring the brain (part 1) Flashcards
What are two things we can investigate from neuropsychology?
- How does damage to a specific brain region affect function?
- Infer normal function from what is missing
What does hippocampal damage and global amnesia suggest?
Hippocampus involved in certain types of memory - episodic rather than procedural
What does PET imaging stand for?
Positron emission tomography
How does PET imaging work?
Inject r____ t____ and detect r____.
B____ of t____ molecules - quantify number of e____ p____ and their a____
radioactive tracer, radiation
Binding, tracer, endogenous proteins, activity
What does MRI stand for?
Magnetic resonance imaging
What are the three key qualities of MRI?
Structural
Functional
Diffusion
What is meant by fMRI being
1. Structural
2. Functional
- Gives structure
- Measures blood oxygenation changes - SURROGATE measure of neuronal activity
MRI scans detect brain regions involved in what?
Colour categorisation
Define ethology
The study of animal behaviour in the context of natural behaviour - focuses on evolution
What are the five types of experiments?
Ethology
Behaviourism
Physiology
Neuroanatomy
Neurophysiology
How can we study the processes underlying behaviour using mice/rats?
Exposure the mice or rats to certain associations and disect how the learn those associations
What does anatomy tell us?
About w____ there is and how c____ are c____
Can label different p____ that are specifically expressed in different cell t____ to see w____ they are and what s____ they are
what, cells, connected
proteins, types, where, shape
What is the main way we figure out anatomy?
By labelling tissue post-mortem
What is the scientific word for recording brain activity
Electrophysiology
What are the input, computation and the output in the peripheral nervous system?
Input - sensory neurons
Computation - central nervous system
Output - motor neurons
Fill in the gaps about grey matter and white matter in the spinal cord…
Grey - where cell ____ of the spinal cord circuitry are to control ____ and ____ ____
White - where the ____ travel - asecending (____ ____put) or descending (____ ____put)
Grey - bodies, reflexes, pain regulation
White - axons, (sensory input), (motor output)
