Is Alzheimer's the result of a widespread, gradually mounting defect in brain biochemistry to which neurons for memory and cognition are particularly vulnerable, like canaries in a coal mine? The goal of this project as outlined in this Neuron paper is to develop the technological capability to measure the spiking activity of every single neuron in the brain simultaneously. Daily rhythms of sleep and metabolism are driven by a biological clock in a structure in the brain made up of 20,000 neurons, all of which can keep daily (circadian) time individually. Genetically identical mice that thoroughly explored a complex cage grew more neurons (shown in black on right) in a key brain region than did mice that explored less (left), new research finds. This episode is called excitotoxicity and is the final outcry from neurons before they take an apoptotic path towards cellular death, causing permanent damage to that brain region. The α-Syn clumps caused progressive loss of dopamine neurons in the connected substantia nigra region of the brain. Some anesthetics directly tap into sleep-promoting neurons in the brain, a study in mice reveals. Tweet This · Email This Post · Print This Post. By Barry Ritholtz - June 11th, 2012, 5:00pm. As pediatric specialists become increasingly aware that surgical anesthesia may have lasting effects on the developing brains of young children, new research suggests the threat may also apply to adult brains. As a result of bottom-up input Such pathological spontaneous activity synchronization evidently interacts with other brain regions (26), and has been shown to be closely related to tinnitus loudness (27, 28) and tinnitus duration (29). For instance, auditory cortex neurons that are deprived of normal thalamo-cortical input due to hearing loss do not become inactive, but “rewire” with excitatory inputs from neighboring neurons (21, 22). His work since then reflects that interest in understanding and treating diseases of the brain. From Mirror Neurons to the Mona Lisa. Many stem cell projects involve maturing stem cells in a lab dish to become a type of neuron that goes awry in particular diseases. Anesthesiologists aren't totally lying when they say they're going to put you to sleep. Visual Art A daylong symposium on November 5, 2005 entitled Visual Art and the Brain sought to explore different facets of the relationship between art and neuroscience. The details of the wiring of the brain – which neurons connect to which other neurons, in what pattern, and with what strength of connection – are what largely determine brain function. It then zips through the brain as a series of electrical signals, passing from neuron to neuron along countless branching pathways until it reaches the nerves that directly implement movement.
