Two photon Microscopy News and Research

RSS

Two-photon microscopy (also known as two-photon fluorescence light microscopy) was invented in 1990 as a new method of imaging live cells and tissues in three-dimensions. Conventional fluorescence microscopy illuminates a specimen through the processes of excitation and emissions.

New method could help doctors better understand how drug abuse affects the brain

A new method for measuring and imaging how quickly blood flows in the brain could help doctors and researchers better understand how drug abuse affects the brain, which may aid in improving brain-cancer surgery and tissue engineering, and lead to better treatment options for recovering drug addicts.

Study suggests potential new treatment for seizures

A study out today in the journal Nature Medicine suggests a potential new treatment for the seizures that often plague children with genetic metabolic disorders and individuals undergoing liver failure. The discovery hinges on a new understanding of the complex molecular chain reaction that occurs when the brain is exposed to too much ammonia.

Study shows how brain integrates inputs from different senses in complex circuits of nerve cells

A new publication in the top-ranked journal Neuron sheds new light onto the unknown processes on how the brain integrates the inputs from the different senses in the complex circuits formed by molecularly distinct types of nerve cells. The work was led by new Ume- University associate professor Paolo Medini.

NIH awards $1.7M grant to develop effective treatments for brain disorders

Ten percent of Americans experience a seizure in their lifetime, with three million diagnosed with epilepsy, a chronic neurological disorder. Anticonvulsant medications can mitigate the hyperactivity of neurons that leads to seizures, but not without severe side effects, including cognitive impairment.

Scientists create way to see structures that store memories in living brain

Oscar Wilde called memory "the diary that we all carry about with us." Now a team of scientists has developed a way to see where and how that diary is written.

Study suggests need for better anti-rejection therapies

Transplant researchers at the University of Pittsburgh School of Medicine challenge a long-held assumption about how biologic pathways trigger immune system rejection of donor organs in a report published online today in the Journal of Clinical Investigation.

WUSTL's Wang receives NSF grant to study oxygen consumption rates of individual cells

When scientists study cells, they need to know how much oxygen each cell consumes to determine its metabolism. However, existing technology limits this study to groups of cells, not individual cells. Lihong Wang, PhD, plans to change that.

New study reveals how control of brain blood flow develops with age

A new study by Columbia Engineering researchers finds that the infant brain does not control its blood flow in the same way as the adult brain. The paper, which the scientists say could change the way researchers study brain development in infants and children, is published in the February 18 Early Online edition of Proceedings of the National Academy of Sciences (PNAS).

New way to image how brain cells coordinate with each other to control specific behaviors

A team led by MIT neuroscientists has developed a way to monitor how brain cells coordinate with each other to control specific behaviors, such as initiating movement or detecting an odor.

Study characterizes movement of rhodopsin

A recent study in The Journal of General Physiology characterizes the movement of rhodopsin, a GPCR and member of a large family of transmembrane receptors responsible for many cellular responses and involved in many human diseases.

UTMB researchers receives NIH grant to develop engineered lung tissue for biomedical studies

University of Texas Medical Branch at Galveston researchers have been awarded a two-year, $1.25 million National Institutes of Health grant to develop a method of custom-growing human lung tissue to make a three-dimensional model for biomedical studies.

Scientists capture high-quality images of immune cell trafficking in a beating heart

Blood flow to the heart often is interrupted during a heart attack or cardiac surgery. But when blood flow resumes, the heart may still falter. That's because collateral damage can occur as blood re-enters the heart, potentially slowing recovery and causing future cardiac troubles.

Researchers track structural changes during formation of new memories

New connections between brain cells emerge in clusters in the brain as animals learn to perform a new task, according to a study published in Nature on February 19 (advance online publication). Led by researchers at the University of California, Santa Cruz, the study reveals details of how brain circuits are rewired during the formation of new motor memories.

Bessel beam plane illumination microscopy reveals 3-D structures of living cells

A new microscope invented by scientists at Howard Hughes Medical Institute's Janelia Farm Research Campus will let researchers use an exquisitely thin sheet of light -- similar to that used in supermarket bar-code scanners -- to peer inside single living cells, revealing the three-dimensional shapes of cellular landmarks in unprecedented detail.

UCLA imaging system could help reveal 'miscommunications' in autism, schizophrenia

Some disorders of the brain are obvious - the massive death of brain cells after a stroke, the explosion in the growth of cells that marks a tumor. Other disorders, such as autism, schizophrenia and mental retardation show no physical signs of damage and are believed to be caused by problems in how brain cells communicate with one another.

New research sheds light on how neurons make connections with one another

Newly published research led by Professor Z. Josh Huang, Ph.D., of Cold Spring Harbor Laboratory sheds important new light on how neurons in the developing brain make connections with one another.

Researchers develop new lung imaging technique that causes minimum tissue disruption

Fast-moving objects create blurry images in photography, and the same challenge exists when scientists observe cellular interactions within tissues constantly in motion, such as the breathing lung. In a recent UCSF-led study in mice, researchers developed a method to stabilize living lung tissue for imaging without disrupting the normal function of the organ.
