For @CurrentBiology, Isaac Chen, MD contributed to a paper where it was learned that odor representations from nostrils are segregated in the piriform cortex, showing an olfactory coding scheme that parses info across nostrils in a single inhalation. ➡️ spr.ly/6014uqMBn

The latest advance in brain organoids. Human neural implants are surprisingly good at integrating with host brains in adult rats. @Penn research could pave the way to treating brain injuries with organoid grafts ft.com/content/d8672e07-2276…

When transplanted into injured adult rat brains, human brain organoids can grow, send out neural signals, and respond to visual stimuli. @PennMedicine Read more in @CellStemCell cell.com/cell-stem-cell/full…

Our team has just published a new paper : authors.elsevier.com/c/1gX1h… in @CellStemCell on the integration of human forebrain organoids with the injured adult rat visual system. Congrats to @DennisJgamadze and the team on this big step! @CellPressNews. Highlights of the study👇🧵

* Organoids transplanted into an injury cavity integrate with adult rat visual system. * We found a polysynaptic pathway between organoid neurons and host retina. * Visual stimulation of host animals showed orientation selectivity in organoids.

Our findings suggest that organoid transplantation may be a clinically relevant approach to neural repair. This research provides insight into the potential for regenerative therapies in the treatment of brain injuries.
