Glutamatergic inputs from the cerebral cortex and dopaminergic inputs from the substantia nigra pars compacta terminate on dendritic spines of medium spiny neurons. The reward-related dopaminergic inputs are thought to mod ...

Purinergic signalling in neuroregeneration
... to trauma or mechanical strain, ATP was released and there was Akt activation. PPADS, a P2 receptor antagonist, attenuated the Akt activation. Trauma-induced activation of purinergic signalling in astrocytes via P2Y4 receptors stimulates the synthesis and release of thrombospondin-1, an extracellula ...

Neurons: What They`re Made Of and How They
... Generally, each cell has only one axon and it leaves the soma at an enlargement called the "axon hillock." The length of axons is greatly variable. They range from a fraction of an inch up to over 3 feet in length. The axon carries signals away from the soma. Some axons are covered with a fatty, whi ...
