Walking changes vision

How do we perceive our environment? What is the influence of sensory stimuli on the peripheral nervous system and what on the brain? Science has an interest in this question for many reasons. In the long term, insights from ...

Where does Parkinson's disease start: In the brain, gut, or both?

Does Parkinson's disease (PD) start in the brain or the gut? In a new contribution published in the Journal of Parkinson's Disease, scientists hypothesize that PD can be divided into two subtypes: gut-first, originating in ...

Parkinson's disease may originate in the intestines

In 2003, a German neuropathologist proposed that Parkinson's disease, which attacks the brain, actually might originate from the gut of the patients. Researchers from Aarhus have now delivered decisive supportive evidence ...

First step to induce self-repair in the central nervous system

Damaged peripheral nerves can regenerate after an injury, for example, following a forearm fracture. Axons, the long projections of neurons that transmit stimuli or signals to other cells, are affected in the case of injury ...

Peripheral nervous system

The peripheral nervous system (PNS) resides or extends outside the central nervous system (CNS), which consists of the brain and spinal cord. The main function of the PNS is to connect the CNS to the limbs and organs. Unlike the central nervous system, the PNS is not protected by bone or by the blood-brain barrier, leaving it exposed to toxins and mechanical injuries. The peripheral nervous system is divided into the somatic nervous system and the sensory system.
