Common brain network for psychiatric illness discovered

Posted by in categories: biotech/medical, neuroscience

Psychiatric illnesses, such as schizophrenia and depression, affect nearly one in five adults in the United States and nearly half of patients diagnosed with a psychiatric illness also meet the criteria for a second. With so much overlap, researchers have begun to suspect that there may be one neurobiological explanation for a variety of psychiatric illnesses. A new study by investigators from Brigham and Womenโ€™s Hospital, a founding member of the Mass General Brigham healthcare system, investigated four pre-existing, publicly available neurological and psychiatric datasets, and pinpointed a network of brain areas underlying psychiatric illnesses. Their results are published in Nature Human Behavior.

โ€œTraditionally, neurology and psychiatry have different diagnostic strategies,โ€ said corresponding author Joseph J. Taylor, MD, Ph.D., Medical Director of Transcranial Magnetic Stimulation at the Brighamโ€™s Center for Brain Circuit Therapeutics and an associate psychiatrist in the Brighamโ€™s Department of Psychiatry. โ€œNeurology asks: โ€˜Where is the lesion?โ€™ and psychiatry asks: โ€˜What are the symptoms?โ€™ We now have tools to explore the โ€˜whereโ€™ question for psychiatry disorders. In this study, we examined whether psychiatric disorders share a common network.โ€

The researchers began by analyzing a set of structural brain data from over 15,000 healthy controls as well as patients diagnosed with schizophrenia, , depression, addiction, obsessive-compulsive disorder, or anxiety. They found gray matter decreases in anterior cingulate and insula, two commonly associated with psychiatric illness. However, only a third of studies showed gray matter decreases in these brain regions. Additionally, also showed gray matter decreases in these same regions.

Automated hippocampal unfolding for morphometry and subfield segmentation with HippUnfold

Posted by in categories: biotech/medical, neuroscience, robotics/AI

Just published from my son.

Automatic hippocampus imaging, with about 20 minutes of cloud computing per scan.


Like neocortical structures, the archicortical hippocampus differs in its folding patterns across individuals. Here, we present an automated and robust BIDS-App, HippUnfold, for defining and indexing individual-specific hippocampal folding in MRI, analogous to popular tools used in neocortical reconstruction. Such tailoring is critical for inter-individual alignment, with topology serving as the basis for homology. This topological framework enables qualitatively new analyses of morphological and laminar structure in the hippocampus or its subfields. It is critical for refining current neuroimaging analyses at a meso-as well as micro-scale. HippUnfold uses state-of-the-art deep learning combined with previously developed topological constraints to generate uniquely folded surfaces to fit a given subjectโ€™s hippocampal conformation. It is designed to work with commonly employed sub-millimetric MRI acquisitions, with possible extension to microscopic resolution. In this paper, we describe the power of HippUnfold in feature extraction, and highlight its unique value compared to several extant hippocampal subfield analysis methods.

Controversy erupts over non-consensual AI mental health experiment

Posted by in categories: neuroscience, robotics/AI

On Friday, Koko co-founder Rob Morris announced on Twitter that his company ran an experiment to provide AI-written mental health counseling for 4,000 people without informing them first, The Verge reports. Critics have called the experiment deeply unethical because Koko did not obtain informed consent from people seeking counseling.

On Discord, users sign into the Koko Cares server and send direct messages to a Koko bot that asks several multiple-choice questions (e.g., โ€œWhatโ€™s the darkest thought you have about this?โ€). It then shares a personโ€™s concernsโ€”written as a few sentences of textโ€”anonymously with someone else on the server who can reply anonymously with a short message of their own.
