Brain Research: Evidence of schizophrenia's causes ♦ Hippo-campus: In search of memory storage ♦ Long-term memory formation

MRI technology reveals deep brain pathways in unprecedented detail A 3-D map of the human brain stem has been produced at an unprecedented level of detail using MRI technology. In a new study, the researchers unveil an ultra high-resolution brain stem model that could better guide brain surgeons treating conditions such as tremors and Parkinson's disease with deep brain stimulation
Scientists produce strongest evidence yet of schizophrenia's causes The strongest evidence yet of what causes schizophrenia has been provided by an international group of scientists. The work strongly suggests that disruption of a delicate chemical balance in the brain is heavily implicated in the disorder.
Hippocampus: In search of memory storage The hippocampus plays a crucial role in memory formation. However, it is not yet fully understood in what way that brain structure's individual regions are involved in the formation of memories. Neuroscientists have recreated this process with the aid of computer simulations. Their findings challenge the model of memory forming in the hippocampus
Autologous stem cell therapy helpful in traumatic brain injury The use of cell therapy after traumatic brain injury in children can reduce the amount of therapeutic interventions needed to treat the patient, as well as the amount of time the child spends in neurointensive care, according to research.
Long-term memory formation Neuroscientists has determined how a pair of growth factor molecules contributes to long-term memory formation The researchers examined GFs in Aplysia californica, the California sea slug. Aplysia is a model organism that is quite powerful for this type of research because its neurons are 10 to 50 times larger than those of higher organisms, such as vertebrates, and it possesses a relatively small network of neurons -- characteristics that readily allow for the examination of molecular signaling during memory formation.
