Brain Circuits for Spatial Memory and Navigation Identified

Researchers have identified two neural circuits in the retrosplenial cortex (RSC) that are critical for spatial navigation and memory storage. The M2-projecting pathway links spatial thought to action, while the AD-projecting pathway supports location-specific memory.

Echolocation Map Helps Bats Navigate Kilometers in the Dark

Researchers have shown that echolocating bats use an acoustic map of their environment to navigate long distances, even after being displaced. In a study on Kuhl’s pipistrelle bats, scientists tracked the bats’ return journeys across a three-kilometer radius using echolocation alone.

Fruit Flies’ Small Neuron Network Defies Navigation Theories

Neuroscientists have uncovered how a small network of neurons in fruit flies accurately maintains an internal compass, defying previous theories that required large networks for precision. This new understanding reveals that small networks, when carefully connected, can perform complex tasks like tracking spatial orientation.

VR Unveils Brain’s GPS Response to Illusions

Researchers successfully induced illusions of self-location in participants using multi-sensory virtual reality (VR). They observed corresponding changes in the brain's grid cells, which are responsible for spatial navigation. This study is the first to demonstrate that purely cognitive changes in self-location, without physical movement or visual cues, can trigger activity in grid cells.

Impaired Spatial Navigation May Signal Early Alzheimer’s

Researchers have pioneered a study using virtual reality (VR) to identify early signs of Alzheimer’s disease through impaired spatial navigation in asymptomatic adults at risk. By testing 100 middle-aged adults with genetic, familial, or lifestyle risk factors for Alzheimer's, the study discovered that spatial navigation difficulties in VR environments precede traditional cognitive decline symptoms.

Endocannabinoids Play Role in Spatial Navigation

Researchers made a new discovery about how we navigate our environments, pinpointing a brain cell mechanism crucial for spatial orientation. This research reveals that place cells in the hippocampus, essential for creating mental maps of our surroundings, activate and release endocannabinoids to communicate position information.
