Neurogenesis and the septotemporal axis at #SFN11

As I’ve alluded, science, and therefore the SFN meeting where much science is unveiled, is a cycle of confusion and clarification. Currently, confusion may be prevailing in the adult hippocampal neurogenesis field since new neurons have been implicated in everything mammals do – spatial and nonspatial memory, anxiety, depression, addiction,…

What I learned while presenting at #SFN11

It’s hard to explore SFN when you’ve got your own poster to tend to. I thought I could hop around the development section before things got busy but there was no “before things got busy.” The design of the conference also can work against presenters because the presentations you’d like…

How to share all of your data

Figshare is one of the greatest new tools for scientists. It allows you to publish any piece of data, no matter how small or insignificant, in a citable fashion. This is a big deal because ALL scientists have (tons of) data of this sort. Pilot experiments are performed to get the…

Dorsoventral vs. Septotemporal hippocampus

Everybody knows what the hippocampus is for: memory. And…maybe something about anxiety or depression? Yes – over the last 10 years or so many studies have been published showing that the hippocampus has these two roles and that the mnemonic and emotional functions of the hippocampus are associated with its…

How does the brain pick which neurons to use?

Wiring. That’s one answer to this question. We know this from topographic maps in the thalamus and neocortex, where the basic units of sensory information are neatly represented in spatially-arranged populations of neurons – the various body parts are represented in specific locations, as are the different frequencies of sound, the different…

Pattern separation: 370,000,000 papers 2050?

If you’ve been paying attention to the adult hippocampal neurogenesis literature at all, you noticed that “pattern separation” is gaining popularity as a research topic. A few quick searches on Pubmed confirm that a trend is indeed afoot.  For the years prior to 1999, only 15 Pubmed-indexed papers answer to…

What IS the dentate gyrus doing to CA3?

A fundamental property of the hippocampus is its ability to rapidly encode memories while simultaneously keeping them distinct. Recording from hippocampal neurons one can clearly see that different populations of neurons are active as a rat explores two environments. This is thought to be one mechanism by which information is…
