Conducting medical research on lab-printed brains could be better than animal studies.
Summary: Researchers have identified two proteins that prevent the formation of scars in the brain and help promote the regeneration of new neural tissue.

LMU researchers demonstrate in a zebrafish model that two proteins prevent scar formation in the brain, thereby improving the ability of tissue to regenerate.
3D structures of cells and connections reveal new role for an understudied brain cell.

TALK ABSTRACT
Life was solving problems in metabolic, genetic, physiological, and anatomical spaces long before brains and nervous systems appeared. In this talk, I will describe remarkable capabilities of cell groups as they create, repair, and remodel complex anatomies. Anatomical homeostasis reveals that groups of cells are collective intelligences; their cognitive medium is the same as that of the human mind: electrical signals propagating in cell networks. I will explain non-neural bioelectricity and the tools we use to track the basal cognition of cells and tissues and control their function for applications in regenerative medicine. I will conclude with a discussion of our framework based on evolutionary scaling of intelligence by pivoting conserved mechanisms that allow agents, whether designed or evolved, to navigate complex problem spaces.
TALK MATERIALS

This educational video about cellular automata was filmed, narrated, and edited by Rudy Rucker in 1990, using some âCA Labâ software he worled on at Autodesk. Renamed âCellab,â the software and manual are available for free on Ruckerâs website.

But certainly you can watch the video without using the software. Two-dimensional CA rules discussed include Langtonâs worm, the game of Life, Silvermanâs Brain, the Vote rule, the Rug rule, gas-simulating rules, and many others.

In the future, can humans control computer-operated machines by simply âthinkingâ?

A group of researchers used optogenetics and brain implants to make mice ignore sex and food.
Video shows a cyborg mouse ignoring sex and food as it obeys humansâ navigation commands.
Augmenting a personâs cognitive ability with BCIs is becoming more science fact that science fiction, with defence personnel likely to benefit.
Researchers discover that to sharpen its control over precise maneuvers, the brain uses comparisons between control signals â not the signals themselves.
