Dendritic spines, small membranous protrusions emerging from a brain cell's dendrite, help to transmit electrical signals to neurons. These spines can have a variety of different shapes, ranging from so-called "stubby" to ...
(Medical Xpress)—Nothing raises the hackles on the neck of a neurobiologist like talk of dendritic spines on neurons. These little outcroppings of membrane and contractile tissue adorn the long apical tendrils of excitatory ...
An international team of scientists has used a wireless "brain-spinal interface" to bypass spinal cord injuries in a pair of rhesus macaques, restoring intentional walking movement to a temporarily paralyzed leg. The researchers, ...
