Memory performance decreases with increasing age. Cannabis can reverse these ageing processes in the brain. This was shown in mice by scientists at the University of Bonn with their colleagues at The Hebrew University of Jerusalem (Israel). Old animals were able to regress to the state of two-month-old mice with a prolonged low-dose treatment with a cannabis active ingredient. This opens up new options, for instance, when it comes to treating dementia. The results are now presented in the journal Nature Medicine.
The thalamus is a small region that sits in the centre of our brain, and is thought to relay signals from our ears, eyes, mouth and skin to other parts of the brain for processing.
But a new study suggests that it's not just passing on information - it also plays a role in cognitive behaviours, such as making decisions and staying focussed.
I have spent much of the last eight months touring neurological facilities across North America and meeting with a number of leading researchers and physicians. There are quite a few new treatments in the pipeline or in early stages of research that have the potential to revolutionize how we deal with Parkinson’s disease.
We all know that if we want what we've studied during the day to stick, it's best to get a good night's sleep. And while scientists have long understood that our memories rely on connections being built between neurons in our brains, it's not been clear how sleep actually helps to consolidate that information.
Now, two new studies have found biological evidence that expains the age-old wisdom that if we want to remember, we need to sleep to forget.
