Previously unknown method of neurotransmission identified.

The neuronal gene Arc is essential for long-lasting information storage in the brain, mediating various forms of synaptic plasticity and is implicated in neurodevelopmental disorders. However, little is known about … Continue Reading Previously unknown method of neurotransmission identified.

Researchers sucessfully make memories stronger and more precise during aging in mice.

It is known that neurons in the central nervous system of higher vertebrates are formed during embryonic development and that neurogenesis does not occur postnatally, except in the hippocampus. Buried … Continue Reading Researchers sucessfully make memories stronger and more precise during aging in mice.

Researchers elevate brain protein to allay symptoms of Alzheimer’s in animal model.

Alzheimer’s disease is characterized by the degeneration of neurons in the hippocampus and cortex, and the appearance of neuritic plaques and neurofibrillary tangles.  Although the precise cause of Alzheimer’s disease remains … Continue Reading Researchers elevate brain protein to allay symptoms of Alzheimer’s in animal model.

Research refutes famous study, shows neurons created through exercise don’t erase old memories.

Exercise is well-known for its cognitive benefits because it causes neurogenesis, the creation of new neurons, in the hippocampus, which is a key brain region for learning, memory and mood … Continue Reading Research refutes famous study, shows neurons created through exercise don’t erase old memories.

Neuroimaging shows how the brain switches from past to present memory mode.

The hippocampus is a critical structure for encoding of novel experiences. A particularly compelling puzzle is how the hippocampus encodes new information in the presence of interference from past memories.  … Continue Reading Neuroimaging shows how the brain switches from past to present memory mode.

Neuroimaging can identify start and location of amyloid plaques in living brain.

Primary progressive aphasia (PPA) is a form of dementia characterized by degeneration of the language network.  In the early stages, PPA is associated with a left-lateralized pattern of cortical atrophy … Continue Reading Neuroimaging can identify start and location of amyloid plaques in living brain.
