Lasers, key to unlocking memory

Lasers, key to unlocking memory

New method uses near infrared light to shed light on memory loss conditions Researchers at Hiroshima University have developed a new laser activated technique for bridging missing links in memory flow. The brainchild of Professor Manabu Abe of Hiroshima Universities Department of Chemistry, it aims to open up the mysterious world of neurotransmission – increasing our understanding of the mechanisms involved and potentially leading to treatments for memory loss conditions.   Gaps in our understanding Memory involves the successful flow of neurotransmitters from neuron to neuron. When memory breaks down, we know there must be a gap in this flow but we currently don’t know where to start in terms… Read more

The tortoise and the hare of spinal neural circuits

The tortoise and the hare of spinal neural circuits

After an injury, practicing movements at different speeds improves certain nerve functions Changes in one circuit of nerves, but not another, in the spinal cord depend on how quickly muscles must move to complete a task, according to results from the Human Motor Control Laboratory of Professor Kozo Funase, PhD, at Hiroshima University.  The results could influence physical therapy routines for patients struggling to control their bodies after a stroke or spine injury. Multiple different types of circuits of nerves control the communication between motor and sensory nerves in the spine.  One, called presynaptic inhibition, works like a gate to control incoming sensory information and prevents muscle spasms.  Another, called… Read more
