Reactivation of specific memories can indirectly strengthen related ones, study finds
Most humans can recall specific events and past experiences for long periods of time. This capability, referred to as episodic memory, is known to be in great part supported by the activity of neurons in the hippocampus and medial temporal lobe.
Past neuroscience and psychology studies consistently found that episodic memory is associative. This essentially means that remembering one past event, for instance a graduation, can in many cases prompt people to also remember other related events, such as a party that celebrated the graduation.
Researchers at Biología Molecular y Neurociencias (IFIByNE)-CONICET and the University of Buenos Aires recently carried out a new study exploring the possibility that the reactivation of specific episodic memories does not only help to strengthen those memories, but also the memories of other related events or experiences.
Researchers contribute to new toolkit for battling brain disorders
New studies stemming from the Armamentarium consortium outline findings that advance tools based on Adeno-associated virus (AAV) vectors. An announcement about the work explains how an AAV “acts like a shuttle capable of transporting specially designed DNA into the cell.”
Two of the studies on these AAV tools were conducted by collaborative teams organized by Xiangmin Xu, Ph.D., UC Irvine Chancellor’s Professor of anatomy and neurobiology and director of the campus’s Center for Neural Circuit Mapping.
“This Armamentarium’s collection of work enables new tools that help to deepen our understanding of the human central nervous system structure and function,” says Xu. “Our own brain-targeting technology could help treat Alzheimer’s disease and many other neurological disorders.”
Valve Founder’s Neural Interface Company to Release First Brain Chip This Year
Valve founder Gabe Newell’s neural chip company Starfish Neuroscience announced it’s developing a custom chip designed for next-generation, minimally invasive brain-computer interfaces—and it may be coming sooner than you think.
The company announced in a blog update that it’s creating a custom, ultra-low power neural chip in collaboration with R&D leader imec.
Starfish says the chip is intended for future wireless, battery-free brain implants capable of reading and stimulating neural activity in multiple areas simultaneously—a key requirement for treating complex neurological disorders involving circuit-level dysfunction. That’s the ‘read and write’ functions we’ve heard Newell speak about in previous talks on the subject.
Gabe Newell on Brain-computer Interfaces: ‘We’re way closer to The Matrix than people realize’
Gabe Newell, co-founder of Valve, sat down with IGN for a chat about the company, the promise of VR, and Newell’s most bleeding edge project as of late, brain-computer interfaces (BCI).
