Brain activity in the hippocampus changes after silencing the enthorinal cortex“We know that the hippocampal neurons generate pulses of activity when the animal is in a particular space,” said co-corresponding author Dr. Daoyun Ji, assistant professor of molecular & cell biology at Baylor.To measure the electrical activity in the hippocampus, the researchers inserted tiny probes – thinner than a human hair – into the brains of mice. “We inserted the probes into the hippocampus where they could detect the electrical signal generated by active neurons. We recorded this signal while the animal explored its surroundings. As the mouse learned its environment, we picked up the electrical pulses produced by the neurons – up to 50 neurons simultaneously – so that we could examine the pattern that emerged. When the animal was in one area of the room, a particular brain pattern emerged. The pattern changed as the animal moved to another area. We could predict where the animal was by looking at its pattern of brain activity,” said Ji.When the researchers turned off the entorhinal cortex with ivermectin, they saw the pattern of electrical signals in the hippocampus changed. Signals that had previously been associated with a particular location now became active in a different part of the room. “We found that the hippocampus had remapped, the memory code was scrambled,” said Ji. But would mice whose mental map had rearranged itself also lose their memory for the location they learned before re-mapping?To answer this question, the researchers trained mice to find a hidden escape platform submerged in a water maze using visual clues. Then some of the mice received ivermectin to inactivate the entorhinal cortex, while others did not. “The mice had been trained for 7 to 10 days, so they knew where to go to escape the pool. But when we turned off the entorhinal cortex, their hippocampal map got scrambled and the animals couldn’t remember how to exit the pool,” said Ji.“Our findings put us one step closer to understanding how our hippocampus may be required not only to learn a new environment, but also to remember it later,” said Jankowsky. “The system we used to silence neurons with ivermectin adds to a growing set of genetic tools created over the last 10 years to probe brain function. Because ivermectin is both safe and inexpensive, this particular system can be used for longer periods of inactivation appropriate for studying chronic conditions like Alzheimer’s or Parkinson’s. That’s the thing I am most excited about with this work,” said Jankowsky. Share on Facebook Email Share Share on Twitter Pinterest LinkedIn Two interconnected brain areas – the hippocampus and the entorhinal cortex – help us to know where we are and to remember it later. By studying these brain areas, researchers at Baylor College of Medicine, Rice University, The University of Texas MD Anderson Cancer Center and the National Cancer Institute have uncovered new information about how dysfunction of this circuit may contribute to memory loss in Alzheimer’s disease. Their results appear in Cell Reports.“We created a new mouse model in which we showed that spatial memory decays when the entorhinal cortex is not functioning properly,” said co-corresponding author Dr. Joanna Jankowsky, associate professor of neuroscience at Baylor. “I think of the entorhinal area as a funnel. It takes information from other sensory cortices – the parts of the brain responsible for vision, hearing, smell, touch, and taste – and funnels it into the hippocampus. The hippocampus then binds this disparate information into a cohesive memory that can be reactivated in full by recalling only one part. But the hippocampus also plays a role in spatial navigation by telling us where we are in the world. These two functions converge in the same cells, and our study set out to examine this duality.”The new mouse model was genetically engineered to carry a particular surface receptor on the cells of the entorhinal cortex. When this receptor was activated by administering the drug ivermectin to the mice, the cells of the entorhinal cortex silenced their activity. They stopped funnelling information to the hippocampus. This system allowed the scientists to turn off the entorhinal cortex, and to determine how this affected hippocampal function.

The Islanders (3-1) lost a tough doubles point on courts one and two as the sophomore duo of Paul Cook and Kevin Bettendroffer dropped their first loss of the season at No. 2 doubles. The pair came up short 6-1 to Nate Lammons and Arkadijs Slobodkins. SMU then captured the doubles point after Arturs Kazijevs and Markus Kerner defeated the senior-junior pair of Peter Nagy and Guillaume Rauseo, 6-4, at No. 1 doubles. After picking up their first doubles win of the season on Tuesday, Arthur Bedel and Mitchell Cook were trailing SMU’s Samm Butler and Tony Russell, 5-2, at No. 3 doubles when the point was clinched. The Mustangs earned their fifth and final point of the day in No. 3 singles after Butler rallied back against Ricardo Mayagoitia after being a set and a break down. Mayagoitia garnered the first set 6-4, before Butler answered back with a 6-4 second-set win and 6-3 third-set victory. SMU carried its momentum over into singles play to take a 3-0 lead after picking up straight-set wins on courts five and six. Javier Pujol fell 6-1, 6-2 to Slobodkins in No. 5 singles for his first loss of the season. P. Cook also came up short in No. 6 singles, 6-3, 6-4 to Charles Nettlefold. SMU battled back from a set and a break down at three and four to claim the victory at home against a scrappy Islander team. At No. 4 singles, Rauseo bested Lammons 6-3, in the first set before Lammons rallied back to top Rauseo 6-4 in the second and 6-1 in the third to give SMU its clinching fourth point. The final four singles matches featured three-setters. Bettendroffer put the Islanders on the board with a come-from-behind victory in No. 2 singles. The sophomore dropped the first set 6-1, before bouncing back to edge Kerner 7-5 in the second set. In the third, Bettendroffer closed out a 6-1 win for his third win of the season. The highlight of the night was Nagy’s thrilling match at No. 1 singles. After dropping the first set, the senior battled back with some great shots in the second and third to win, 1-6, 6-3, 7-5 over Kazijevs, who was ranked in the ITA national rankings last season. SMU 5, Texas A&M-Corpus Christi 2DALLAS, Texas – The Texas A&M-Corpus Christi men’s tennis team suffered a heartbreaking 5-2, loss tonight against a very tough SMU squad at the SMU Indoor Tennis Complex. The Mustangs (7-1) clinched the doubles point before securing four of the six singles matches. The men will remain on the road to face Texas Tech in Lubbock, Texas on Saturday, Feb. 14, at 1 p.m.
Working as a security guard can be a dangerous and thankless job. Now Knightscope wants robots to do it for us. The Mountain View, Calif., startup has been building and testing a robot model known as the K5 for this purpose since 2013, MIT Technology Review reports. Now the robot fleet is advanced enough to patrol Microsoft’s Silicon Valley campus. See also: R2-D2? Dalek? Actually, It’s A Pre-Cog RobocopAt five feet tall and 300 pounds, the K5 is an ambulatory robot with semi-human proportions. Sleek and smooth, it is supposed to look friendly from a distance, but intimidating close up. It doesn’t carry weapons and it can’t hurt people, but it will beep ominously if you try to detain it while sending an alert to a remote monitoring center. (Early models still have a serious vulnerability—push them over and they can’t get up without assistance.)On the other hand, the K5 can also be a friendly presence. If you need help, you can press a button on the top of the robot’s head to summon a human operator. “This takes away the monotonous and sometimes dangerous work, and leaves the strategic work to law enforcement or private security, depending on the application,” Knightscope cofounder and vice president of sales and marketing Stacy Stephens told MIT. (Translation: Low-wage security guards, you’re out of a job. K5 will now escort you from the premises.)See also: China Doubles Down On RoboticsThe robots use Wi-Fi to communicate with one another and with human operators. They include four high-definition cameras on either side of the robot, a license plate recognition camera, four microphones, and a weather sensor. Stephens did not disclose how much the K5 will cost, but noted that potential customers include security companies, office buildings, and schools.
