Recently, thermogenetic methods (Hamada et al. 2008; Peabody et al. 2009) have been developed to control neural activity with temperature-activatable ion channels, creating an effective way to activate neurons in large numbers of flies for genetic screening.
How about chips implanted in the brain to control neural activity, Matrix-style?
"It's so difficult to get anything to work in the human brain at all," says Ed Boyden, an MIT neuroscientist who discussed his work using light to control neural activity, which could be developed into a treatment for blindness.
This ability to bidirectionally control neural activity allowed us to disrupt precise spike timing of neural activity without altering spike rate, a long-desired tool for systems neuroscientists interested in the role of synchronous or precisely timed neural activity in the brain.
Today, most studies, even those using optogenetics to control neural activity, rely on DAT-Cre or TH-Cre for targeting of DA cells.
DOI: http://dx.doi.org/10.7554/eLife.07192.025 Like the optoclamp, the voltage clamp relies on a continuously updated feedback loop to control neural activity.

The recent development of optogenetics especially has allowed us to control neural activities more precisely than ever before.
New photochemical tools for controlling neural activity.
Whole brain analysis of group-by-empathy interaction revealed that when participants judged the behavior during the attribution phase, several brain regions implicated in mentalizing distinguished patients from controls: In healthy controls, neural activity scaled negatively with empathy, but this relationship was reversed in BPD patients.
Our implementations of the optoclamp are quite reliable for controlling neural activity in cultured networks and thalamic cells in vivo and the technique's simplicity lowers the barrier for its adoption.
The capacity of the brain to organize sensory input into precise movements, thoughts, emotions, and memories is the culmination of thousands of protein complexes organized spatially within neurons and astrocytes to control neural connectivity, activity, and plasticity.
Write better and faster with AI suggestions while staying true to your unique style.
Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
