Remembrance of things future: Long-term memory sets the stage for visual perception
(Medical Xpress) -- Rather than being a passive state, perception is an active process fueled by predictions and expectations about our environment. In the latter case, memory must be a fundamental component ...

The brain on drugs: Defining the neural anatomy and physiology of morphine on dopamine neurons
(Medical Xpress) -- Morphine's analgesic properties are as potent as its addictive potential are problematic. The neural pathway for that addiction is typically associated with dopamine (DA) neurons of the ...

Branching out: A mathematical law of dendritic connectivity
(Medical Xpress) -- That the brain is evolution at its finest is perhaps best demonstrated by the beauty, complexity and diversity of dendrites – tree-like structures that form neural circuits by connecting ...

Do brain cells need to be connected to have meaning?
(Medical Xpress)—The classic theory of the brain is one of connections, in which the brain consists of a network of neurons that interact with each other to allow us to think, see, interpret, and understand ...

Women's, men's brains respond differently to hungry infant's cries
(Medical Xpress)—Researchers at the National Institutes of Health have uncovered firm evidence for what many mothers have long suspected: women's brains appear to be hard-wired to respond to the cries of a hungry infant.

Of mice and mental models: Neuroscientific implications of risk-optimized behavior in the mouse
(Medical Xpress) -- Regardless of an organism’s biological complexity, every encephalized animal continuously makes under-informed behavioral choices that can have serious consequences. Despite its ubiquity, ...

Neural codes for memory implants
(Medical Xpress)—The ability to short-circuit debilitating tremors in disease states with implantable stimulators is nothing short of remarkable. The same can be said for cochlear prosthetics which restore ...

Think fast: Speed of thought and perception limited by unified neocortical gateway
(Medical Xpress) -- Historically, perceptual and response rates when multitasking have been interpreted as being limited by independent bottlenecks. While a more recent view suggests that a common bottleneck ...

Seeing is as seeing does: Spatially-structured retinal input in early development of cortical maps
(Medical Xpress) -- Remarkably, cortical maps show that neurons in the primary visual cortex have specific preferences for the location and orientation of a given visual field stimulus – but how these ...

Blink if your brain needs a rest
Why do we spend roughly 10 percent of our waking hours with our eyes closed - blinking far more often than is actually necessary to keep our eyeballs lubricated? Scientists have pried open the answer to this ...

Rats take high-speed multisensory snapshots
When animals are on the hunt for food they likely use many senses, and scientists have wondered how the different senses work together. New research from the laboratory of CSHL neuroscientist and Assistant Professor Adam ...
