Stroke induces a plastic state in the brain. This period of enhanced plasticity leads to the sprouting of new axons, the formation of new synapses and the remapping of sensory-motor functions, and is associated
The action potential of the squid giant axon is formed by just two voltage-dependent conductances in the cell membrane, yet mammalian central neurons typically express more than a dozen different types of voltage-dependent ion channels. This rich repertoire of channels allows neurons to encode infor...
Monitoring of NADH fluorescence, as an indicator for mitochondrial function, started by using isolated mitochondria from various organs. This in vitro monitoring approach was applied, later on, to various organs monitored in the intact animal in vivo. In
In this review, we discuss the importance of cellular NAD+ in aging, neurodegeneration, metabolic disorders, and cancer. 2. NAD+ biosynthesis pathways The intracellular concentration of NAD+ is a balance between NAD+ consumption and synthesis. The biosynthetic pathways of NAD+ play an important ...
They are thought to be caused by the inherent electrical charges the retina produces even when it is in its "resting state" and not taking in a ton of information and light like it does when our eyes are open. Emotional brains 'physically different' from rational ones Science Daily - ...
RhoA is thought to promote condensation of the actin network in neurite tips acting as a negative regulator of both axon specification and axon growth [14] and therefore having a role in the establishment of neuronal polarity [5, 13, 15, 16, 17, 18, 19]. Consistently, molecular ...
Once the cell reaches a certain threshold, it will cause an action potential, which sends the electrical signal down the axon. Before this happens and before an impulse can fire, it must come from a state of readiness. Answer and Explanation: The...
The IAS plays an important role maintaining faecal continence. In the normal resting state, the IAS is contracted and it has a basal tone. It is estimated that in humans the IAS contributes some 50–85 % of total anal sphincter tone (Lestar et al.1989; Cook et al.2001; Bharucha2006,200...

However, they remain distinct in the thalamus. A strong remapping of sensory responses accompanies this dynamic state change produced by anesthesia. Together, these results show that the awake cortex engages dedicated neuronal assemblies in response to sensory inputs, which we suggest is a network ...
