Cajal looked under the microscope at different parts of the brain and said, ‘It’s not like a fishing net,’“ Swanson says. "There are individual units called nerve cells or neurons that are put together in chains to form circuits.

It’s amazing how detailed drawings were in the medical field during these early times. "The model of the nerve cell that everybody still learns is the one that Cajal laid out basically in the 1890s"

New guideline on how to map brain prior to epilepsy surgery — ScienceDaily

neuroscienceresearch:

Before epilepsy surgery, doctors may consider using brain imaging to locate language and memory functions in the brain instead of the more invasive procedure that is commonly used, according to a guideline. It is the first evidence-based guideline that systematically reviewed all evidence for such an evaluation.

By constantly reminding the immune system what the parasite that causes leishmaniasis looks like, a persistent infection keeps the immune system on alert against new encounters, even while it carries the risk of causing disease later in life

Persistent Infection Keeps Immune System on Alert, Leading to Long-term Protection

Which is better? Long-term immunity with the cost of persistent infection OR complete riddance at the cost of becoming infected again

I think I agree that control persistent infection probably has the most robust evolutionary advantage here as if you are in an area where you are exposed to one of these pathogens it is probably best to harbor long term immunity. 

It would be interesting to determine in a follow-up study if location/exposure to conspecific external pathogens increases the duration that the immune system reserves these pathogens.

We accept the following as provisionally true:

  • The Earth is becoming warmer due to human action.
  • The diversity of life arose by evolution.
  • An American government that ignores science to pursue ideological agendas threatens not only the environment of which humans are a part, but America itself.
  • Scientific research in the United States is underfunded.
  • Politicians who devalue expertise risk making decisions that do not reflect reality.

Who can participate:

Science is a methodology and a way of thinking. Anyone who uses and values these tools for understanding the world, not just professional scientists, may participate.

How can I help?  

We are still in the very early stages of organizing this event. We need all the help we can get, especially from people with expertise in the following areas:

  • Web Design
  • Logo/Graphic design
  • Law, incorporation of a not-for-profit
  • Fundraising
  • Public relations and media relations
  • Social media management
  • Organizing large events
  • Acquiring permits in DC
  • Contacts with possible speakers

You don’t need to be a professional scientist to participate!

What you see is a myosin protein dragging an endorphin along a filament to the inner part of the brain’s parietal cortex which creates happiness. Happiness. You’re looking at happiness

Well not exactly.. this is a kinesin motor protein walking along a cytoskeletal filament (probably actin) attached to a vesicle which could be carrying dopamine 🤓
