A team of researchers studying the brain have discovered a brand new and previously unidentified form of “wireless” neural communications that self-propagates across brain tissue and is capable of leaping from neurons in one part of the brain to another, even if the connection between them has been severed.
The discovery by biomedical engineering researchers at Case Western Reserve University in Cleveland, Ohio could prove key to understanding the activity surrounding neural communication, as well as specific processes and disorders in the central nervous system.
The discovery also upends the traditional understanding of neural communication, which had previously been thought to consist in such modes as synaptic transmission, axonal transmission and gap junction connections between neurons.
Lead researcher and neural and biomedical engineer Dominique Durand told Case Western’s The Daily that while the implications of their find could be massive, they are still barely beginning to understand the discovery:
“We don’t know yet the ‘So what?’ part of this discovery entirely … But we do know that this seems to be an entirely new form of communication in the brain, so we are very excited about this.”
While the brain still largely remains a mystery, scientists had been aware that it sends out small neural waves that generate small amounts of electrical energy. However, the electric fields were thought to have been too small to result in any sort of neural activity.
However, Durand’s team was able to discover that these fields are not only capable of exciting neighboring cells, but can self-produce waves of activity that cross gaps of the brain – including a gap of brain tissue that was entirely severed.
During an experiment, the brain-wave “leaped” across an empty gap repeatedly – similar to a stadium fan “wave” during a home-run that continues to spread even as some onlookers might remain seated.
“We’ve known about these waves for a long time, but no one knows their exact function and no one believed they could spontaneously propagate … I’ve been studying the hippocampus, itself just one small part of the brain, for 40 years and it keeps surprising me.”
The Journal of Psychology review committee requested that the Case Western researchers replicate the experiment prior to publishing their work, but Durand noted that “every experiment we’ve done since to test it has confirmed it so far.” The paper was published in the October issue of the journal.
Durand remains proud of the discovery, which he found impossible to believe when he first saw it – as did members of his team and a colleague at Tianjin University in China.
“It was a jaw-dropping moment … for us and for every scientist we told about this so far.”
Dolphin Swims Through Louisiana Neighborhood in Aftermath of Hurricane Ida
A Louisiana family was shocked to find a dolphin swimming through their neighborhood in the aftermath of Hurricane Ida.
Amanda Huling and her family were assessing the damage to their neighborhood in Slidell, Louisiana, when they noticed the dolphin swimming through the inundated suburban landscape.
In video shot by Huling, the marine mammal’s dorsal fin can be seen emerging from the water.
“The dolphin was still there as of last night but I am in contact with an organization who is going to be rescuing it within the next few days if it is still there,” Huling told FOX 35.
Ida slammed into the coast of Louisiana this past weekend. The Category 4 hurricane ravaged the power grid of the region, plunging residents of New Orleans and upwards of 1 million homes and businesses in Louisiana and Mississippi into the dark for an indefinite period of time.
Officials have warned that the damage has been so extensive that it could take weeks to repair the power grid, reports Associated Press.
Also in Slidell, a 71-year-old man was attacked by an alligator over the weekend while he was in his flooded shed. The man went missing and is assumed dead, reports WDSU.
Internet users began growing weary last year about the steady stream of stories belonging to a “nature is healing” genre, as people stayed indoors and stories emerged about animals taking back their environs be it in the sea or in our suburbs.
However, these latest events are the surreal realities of a world in which extreme weather events are fast becoming the new normal – disrupting our lives in sometimes predictable, and occasionally shocking and surreal, ways.
Mom in LA Suburbs Fights Off Mountain Lion With Bare Hands, Rescues 5-Year-Old Son
A mother in Southern California is being hailed as a hero after rescuing her five-year-old son from an attacking mountain lion.
The little boy was playing outside his home in Calabasas, a city lying west of Los Angeles in the Santa Monica Mountains, when the large cat pounced on him.
The 65-pound (30 kg) mountain lion dragged the boy about 45 yards across the front lawn before the mother acted fast, running out and striking the creature with her bare hands and forcing it to free her son.
“The true hero of this story is his mom because she absolutely saved her son’s life,” California Department of Fish and Wildlife spokesman Captain Patrick Foy told Associated Press on Saturday.
“She ran out of the house and started punching and striking the mountain lion with her bare hands and got him off her son,” Foy added.
The boy sustained significant injuries to his head, neck and upper torso, but is now in stable condition at a hospital in Los Angeles, according to authorities.
The mountain lion was later located and killed by an officer with the California Department of Fish and Wildlife, who found the big cat crouching in the bushes with its “ears back and hissing” at the officer shortly after he arrived at the property.
“Due to its behavior and proximity to the attack, the warden believed it was likely the attacking lion and to protect public safety shot and killed it on sight,” the wildlife department noted in its statement.
The mountain lion attack is the first such attack on a human in Los Angeles County since 1995, according to Fish and Wildlife.
The Santa Monica Mountains is a biodiverse region teeming with wildlife such as large raptors, mountain lions, bears, coyote, deer, lizards, and snakes. However, their numbers have rapidly faded in recent years, causing local wildlife authorities to find new ways to manage the region’s endemic species.
Video Shows Taliban Taking Joyride in Captured US Blackhawk Helicopter
The rapid fall of Kabul to the Taliban has resulted in a number of surreal sights – from footage of the Islamist group’s fighters exercising at a presidential gym to clips of combatants having a great time on bumper cars at the local fun park.
However, a new video of Taliban members seemingly testing their skills in the cockpit of a commandeered UH-60 Black Hawk helicopter shows the chilling extent to which U.S. wares have fallen into the hands of a group it spent trillions of dollars, and exhaustive resources, to stamp out.
In the new video, shared on Twitter, the front-line utility helicopter can be seen taxiing on the ground at Kandahar Airport in southeastern Afghanistan, moving along the tarmac. It is unclear who exactly was sitting in the cockpit, and the Black Hawk cannot be seen taking off or flying.
It is unlikely that the Taliban have any combatants who are sufficiently trained to fly a UH-60 Black Hawk.
The helicopter, which carries a $6 million price tag, is just a small part of the massive haul that fell into the militant group’s hands after the country’s central government seemingly evaporated on Aug. 14 amid the withdrawal of U.S. and coalition troops.
Some 200,000 firearms, 20,000 Humvees and hundreds of aircraft financed by Washington for the now-defunct Afghan Army are believed to be in the possession of the Taliban.
The firearms include M24 sniper rifles, M18 assault weapons, anti-tank missiles, automatic grenade launchers, rocket-propelled grenades and mortars.
Taliban fighters in the elite Badri 313 Brigade have been seen in propaganda images showing off in uniforms and wielding weaponry meant for the special forces units of the Afghan Army.
The U.S. is known to have purchased 42,000 light tactical vehicles, 9,000 medium tactical vehicles and over 22,000 Humvees between 2003 and 2016.
The White House remains unclear on how much weaponry has fallen into Taliban hands, with National Security Adviser Jake Sullivan admitting last week that the U.S. lacks a “clear picture of just how much missing $83 billion of military inventory” the group has.
