- a form of plasticity following damaged through trauma, the brains ability to redistribute or transfer functions performed by a damaged area to other undamaged areas
- Functional Recovery After Trauma
- case studies of individuals suffering from strokes have found some individuals were able to recover previous functioning to some degree
- The found the brain was able to 're-wire' itself and create alternative neural pathways around damaged areas
- Able to do this through two mechanisms: neuronal masking and stem cells
- Neuronal masking - axon sporuting as new nerve endings grown and connoect to undamaged areas
- Reforming of blood vessels
- Stem cell - unspecialised cells which have the potential to develop into various types of cells with different functions .
- Treatment involving stem cells to inject them into the brain to replace dead or dying cells.
- Can hellp the regeneration of damaged cells through secreting growth factors.
- Evidence for stem cells aiding recovery - TARIJI ET AL - used rats with brain iinjuries while the other were a control group. Only the injured rats received stem cell implants into the areas of the injured brain and after 3 months they showed clear development of neuron-like cells on the injury sites
- Control group the opposite.
- Extrapolation - rats have different biology than human and the findings may lack external validity when generalizing to humans
- Control group the opposite.

- Functional Magnetic Resonance Imaging
- Measures changes to particular areas of the brain while individuals engage in various tasks
- FMRI is non-invasive - not exposing brain to harmful radiation
- Very expensive compared to other neuron technology machines
- Measures changes to particular areas of the brain while individuals engage in various tasks
- Electroencephalogram
- Measures the general state of the brain. By measuring electrical activity in the brain through electrodes placed on the head which detects electrical activity of the brain cells.
- Useful in clinical diagnosis, e.g. recording the abnormal neural activity associated with epilepsy.
- Not useful for pinpointing the exact source of an acitivty
- Useful in clinical diagnosis, e.g. recording the abnormal neural activity associated with epilepsy.
- Measures the general state of the brain. By measuring electrical activity in the brain through electrodes placed on the head which detects electrical activity of the brain cells.
- Event-related potential
- Able to measure processing of stimulus
- Time- consuming
- Uses electrodes to measure very small voltage changes within the brain.
- Post-mortem examination
- Helps establish the underlying neurobiology for people that display particular sets of behaviour.
- Played an essential role in understanding of schizophrenia
- Hard to give informed consent if someone is dead
