A 'bird's eye view' of how human brains operate
A new study provides the best evidence to date that the connection patterns between various parts of the human brain can tell scientists the specialized functions of each region.

Simultaneously Determining Regional Heterogeneity and Connection Directionality from Neural Activity and Symmetric Connection
The spatiotemporal patterns of neural dynamics are jointly shaped by directed structural interactions and heterogeneous intrinsic features of the neural components. Despite well-developed methods for estimating directionality in network connections from network of homogeneous nodes, how local heterogeneity impacts on directionality estimation remains poorly understood. In particular, the role of excitatory-inhibitory interactions in shaping network directionality and how these interactions shou…

Triangular neural synchronization patterns in visual impairment: A comprehensive case series exploring multi-node network dynamics and the Neural Triangle Index (NTI)

Triangular Neural Synchronization Patterns in Visual Impairment: A Comprehensive Case Series Exploring Multi-node Network Dynamics and the Neural Triangle Index
Background: Compensatory neural plasticity in visual impairment involves complex reorganization of multi-node networks that goes beyond conventional bilateral connection analysis. Triangular synchronization patterns, representing coordinated activity among three cortical sites simultaneously, remain unexplored despite their potential to reveal fundamental mechanisms underlying compensatory neuroplasticity. Objective: This study aimed to conduct a case series examining triangular neural synchro…

Content warning: "AI notetakers", little cautionary tale

Hadn't seen this variation before.
Recently, a colleague has had that thing where, un-asked-for by them, their "AI notetaker" tries to go to all the meetings in their calendar. This time it was double trouble: they somehow had _two_ bots trying to come into every meeting citing their name. Consequently, a few of us have had to boot out these bots at the start of a meeting, when the person themself wasn't there.
Yesterday, the _real_ person tried to go to a meeting. The host (who was a bit flustered due to connection problems) mistook their name for the bot appearing yet again, and kicked them out! so they missed the meeting!
(I found out only afterwards that they'd been trying to get on, and what had happened.)

Luckily it wasn't a meeting which hinged on this one person's presence, so not super high stakes. I was just thinking about it again now, and the phenomenon of "unwanted bot-behaviour causes knock-on problem". It reminded me of this more-troublesome episode, which I'd also read about yesterday:
