(Medical Xpress)—The apparent ease and immediacy of human perception is deceptive, requiring highly complex neural operations to determine the category of objects in a visual scene. Nevertheless, the human brain is able ...
(Medical Xpress)—The brain's two hippocampal formations – one in each hemisphere's temporal lobe, medial to the inferior horn of the lateral ventricle and typically referring to the dentate gyrus, the hippocampus proper ...
(Medical Xpress)—In the battle against aging and age-related neurological diseases such as Parkinson's and Alzheimer's, a key factor has long appeared to be the toxicity of proteins which tend to aggregate. Recently, scientists ...
(Medical Xpress)—Scientists have historically relied on neuroimaging – but not electrophysiological – data when studying the human default mode network (DMN), a group of brain regions with lower activity during externally-directed ...
(Medical Xpress) -- That the brain is evolution at its finest is perhaps best demonstrated by the beauty, complexity and diversity of dendrites – tree-like structures that form neural circuits by connecting a neuron ...
(Medical Xpress) -- Regardless of an organism’s biological complexity, every encephalized animal continuously makes under-informed behavioral choices that can have serious consequences. Despite its ubiquity, however, ...
(Medical Xpress) -- On the complex road to eradicating cancer, controlling or preventing metastatic growth initiated by primary tumors is high on the to-do list. A key area of such research is the development of therapies ...
(Medical Xpress) -- Remarkably, cortical maps show that neurons in the primary visual cortex have specific preferences for the location and orientation of a given visual field stimulus – but how these maps develop and ...
(Medical Xpress) -- The link between dreaming and rapid eye movement (REM) sleep are well understood – but the fact that consciousness is reduced during nonrapid eye movement (NREM) sleep is not. Recently, scientists ...
(Medical Xpress) -- College and cramming – often where’s there’s one, the other is not far behind. That said, however, it has been recognized since the late 1800s that repeated periodic exposure to the same ...
