The brain is an important organ that controls all sensory and motor actions, memory, and emotions. Each anatomical and physiological modulation in various brain centers, results in psychological, behavioral, and sensory-motor changes. Alcohol and addictive drugs such as opioids and amphetamines have been shown to exert a great impact on brain, specifically on the hippocampus. Emerging evidence ...

Hereditary sensory and autonomic neuropathy type 1 (HSAN1) is characterized by a loss of distal peripheral sensory and motorneuronal function, neuropathic pain and tissue necrosis. The most common cause of HSAN1 is due to dominant mutations in serine palmitoyl-transferase subunit 1 (SPT1). SPT catalyses the condensation of serine with palmitoyl-CoA, the initial step in sphingolipid biogenesis. ...

Studying the development and mechanisms of sensory perception is challenging in organisms with complex neuronal networks. The worm Caenorhabditis elegans possesses a simple neuronal network of 302 neurons that includes 60 ciliated sensory neurons (CSNs) for detecting external sensory input. C. elegans is thus an excellent model in which to study sensory neuron development, function, and behavio...
