🧠 How does the #hippocampus keep a spatial map stable while adding aversive context?

Miguel-López et al. show that in mice running on a linear belt, #CA3 #axonal population activity preserved a common spatial #manifold across baseline, air puff and probe sessions. The aversive cue did not erase the map, but deformed it, embedding affective information into the same #representational geometry:

🧠 New preprint by Garcia-Garcia et al.: The authors show that cerebellar #GranuleCells do not simply expand #cortical activity into a high-dimensional code. Instead, they preserve low-dimensional cortical #manifold geometry while reorienting it across contexts. This rotation separates similar tasks, reduces interference, and supports flexible dual-task learning.

For over five years the battery charger for our electric bicycle has been awkwardly dangling from a little hook.

With emotional support from toddler and actual support from #FreeCAD I finally created a simple wall bracket.

It's available from .stl sharing site #manifold :-)

Inner dimensions are 73mm by 42,5mm. With a hole in the bottom for a cable exit. Probably fits other chargers as well.
