Have any drugs been shown to increase the neuroplasticity of adult brains?

I read recently in the book "meet your happy chemicals" that the hormones of puberty are neurochemicals that cause your neurons to connect and myelinate more easily. If this is true have any studies ...

Do the colour blind have a distinct visual cortex structure?

Studying the structure of the visual cortex, it seems there are many neural structures specifically dedicated to detecting and interpreting colour. For example, parvocellular cells are particularly ...

Is there a difference between the time/effort it takes for the blind and the sighted to learn to read Braille?

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 ...

How does the timing work out for dopamine to affect the development of long-term potentiation?

I just recently learned (indirectly from this source) that long-term potentiation/depression only takes place when you have large/small amounts of dopamine present at the relevant synapse. However, my ...

What analogy can a teacher use to teach a child about neuroplasticity?

What analogy can a teacher use to teach a child about neuroplasticity? It'd be easier to explain this to an adult, but a child probably doesn't know enough to understand neuroplasticity. Do you know ...

Can reduced cognitive load lead to some kind of mental or physical “atrophy”?

Muscles, if you don't use them, degenerate. Everyone who has had a broken leg in a cast for a few weeks and then seen the thin stick that reemerged once the cast was removed, can attest to that fact. ...

What is the lifetime of the synapse in the mature brain?

I know there is synaptic plasticity in the mature brain. There is a great number of plasticity mechanisms like LTD and LTP, acting on different time scales. Apart from the synaptic weight change, ...

Why does neuroplasticity decrease in adults?

Although adult brains are malleable and even undergo limited neuorgenesis, the extent of the neuroplasticiy is much lower than in children. This is most obvious in language acquisition, and recovery ...
