Here's a short selection of our favorite neuroscience stories from the last week!
The Swiss EPFL’s Blue Brain Project is a vast effort with the goal of digitally reconstructing and simulating the mouse brain and ultimately, the human brain. The recent publication of a Cell Atlas of the mouse brain sounds exciting, but what can the Atlas tell us, and can it bring us closer to a simulated brain?
1. By measuring the fast electrical spikes of individual neurons in the touch region of the brain, neuroscientists have discovered a new type of cell that keeps time so regularly that it may serve as the brain's long-hypothesized clock or metronome.
2. Apathy is the most common neuropsychiatric symptom of dementia, with a bigger impact on function than memory loss - yet it is under-researched and often forgotten in care. A new study has found that apathy is present nearly half of all people with dementia, with researchers finding it is often distinct from depression.
3. A new study has concluded that people who wear a hearing aid for age-related hearing problems maintain better brain function over time than those who do not.
4. A new study has shown that videogames, when used as part of an emotional intelligence training program, can help teenagers evaluate, express, and manage their own emotions immediately after the training.

5. A new study by Montreal scientists published today in Nature demonstrates that a gut infection can lead to a pathology resembling Parkinson's disease (PD) in a mouse model lacking a gene linked to the human disease.
