Seeing Double: Scientists Discover Second Visual System in Mouse Cerebral Cortex

News   Jan 04, 2019 | Original Press Release from UCSF

Seeing Double

In contrast to the dogma that all visual areas in the cerebral cortex get their inputs from primary visual cortex (V1), the new study shows that postrhinal cortex (POR) gets information about moving objects via a parallel visual pathway from an evolutionarily ancient brainstem area called superior colliculus. (The two parallel visual pathways are routed through distinct relay stations in a brain structure called the thalamus: dLGN for V1 and the Pulvinar for POR.) Credit Scanziani lab / UCSF.



Choosing to Own a Pooch May Be a Decision Influenced by Your Genetics


Scientists have studied the heritability of dog ownership using information from 35,035 twin pairs from the Swedish Twin Registry. The new study suggests that genetic variation explains more than half of the variation in dog ownership, implying that the choice of getting a dog is heavily influenced by an individual's genetic make-up.


Crossword Addicts Have Better Brain Function


Older adults who regularly take part in word and number puzzles have sharper brains, according to the largest online study to date. The more regularly adults aged 50 and over played puzzles such as crosswords and Sudoku, the better their brain function, according to research in more than 19,000 participants, led by the University of Exeter and King's College London.


A New Model of Working Memory


A new study presents a new model of working memory that aims to account for the remarkable flexibility of this type of memory.
