How can different ion channels of the same type have different cell responses?

The NMDA receptor is an ion channel and contributes to synaptic plasticity and memory. It is said that calcium ion flux through the receptor is critical for this mechanism. However, there are other ...

Scaling of Ca2+/biochemical signals with dendritic spine size?

I am looking for references that discuss the scaling of biochemical signals in dendritic spines with spine size/synaptic strength. A recent paper (Walker et al. 2017) reports attenuation of NMDA ...

How fast the brain recover itself at sleep? What can be done to accelerate this process?

In Computer Science we have "Big O Notation" to describe how efficient is an algorithm at processing some task. Those can be linear, time constant, exponential among others. Using that analogy, How ...

Plasticity between excitatory and inhibitory neurons?

All that I've learned about synaptic plasticity only concern the synapses between excitatory neurons. For example, all pyramidal neurons (excitatory) in the cortex have plastic synapses between them, ...

NMDA receptor mediated plasticity figure reference

Because most of this research is over a decade old, finding a paper with a figure that clearly shows that (neuronal) synaptic plasticity (such as long-term potentiation/LTP) is NMDA receptor mediated ...

Synaptic connectivity in the newborn's brain

In my understanding, learning is related to the strengthening and weakening of synaptic connections. Very roughly said: Synaptic connections that are used often are strengthened, those that are used ...

What exactly is neuroplasticity, and can it be demonstrated with a simple experiment?

As far as I know, neuroplasticity is about restoring brain functions by moving some functions to other still functional. Neuroplasticity is more prominent in children than in adults. What are other ...

Using perceptual adaptation for enhancing realism of VR/other entertainment

I am quite a fan of the recent oculus rift VR glasses, but it does have several flaws over normal vision, most notably a much less wide field of view, the so-called screen door effect because of too ...

Do blind people learn Braille equally fast as the sighted?

The visually deprived brain undergoes extensive remodeling due to cross-modal plasticity. This leads to increased areas of the cortex being available for other purposes such as tactile processing. Now ...
