Clinical Trend of the Week (Aug 8 -14): Memory Binding Test Recently, neurologist Dr. Richard B. Lipton presented research at the Alzheimer’s Association International Conference (AAIC) regarding the Memory Binding Test (MBT). Memory binding is the process of linking memories, and the test gauges “associative binding” through word lists that test takers are asked to remember. Lipton suggests that older adults who perform poorly on the MBT have an increased risk of amnestic mild cognitive impairment and dementia. Physicians mostly likely searched for more information about this test i... mais »

When I started this work, research on this brain region was a lonely field of inquiry. The hippocampus was all therage, and I sometimes felt jealous of the attention lavished on this brain region because of its contribution to memory.

Neuroskeptic The Rise and Fall of Neurotransmitters By Neuroskeptic | August 15, 2015 5:46 am There are dozens of neurotransmitters in the human brain. How do neuroscientists decide which transmitters are most important? Are there trends and fashions in neuroscience, such that some transmitters rise and fall in popularity? I searched PubMed for nine different neurotransmitters, and downloaded the ‘Results by Year’ data to track the number of peer-reviewed papers published each year from 1960 to 2014. The results are very interesting: [image: neurotransmitters2] Here are some of my obs... mais »
