Metaphorical Brain Talk in Psychiatry: A Historical and Contemporary Perspective

2025-09-07

This essay examines the persistent use of "metaphorical brain talk" in psychiatry, where mental illnesses are explained using simplistic notions of brain structure or dysfunction. From early 20th-century critiques by influential figures like Adolf Meyer and Karl Jaspers, to more contemporary examples involving researchers like Paul Meehl and Nancy Andreasen, the essay traces the enduring presence of this metaphorical language. Despite advances in neuroscience, phrases like "synaptic slippage" and "broken brain" remain commonplace. The author uses the monoamine neurotransmitter hypothesis as a case study, highlighting its limitations in explaining disorders like schizophrenia, mania, and depression. A real-world anecdote illustrates the impact of such metaphorical explanations on patients and the public. The essay concludes by noting that the pursuit of external funding and pharmaceutical advertising have exacerbated the prevalence of this phenomenon.

Mice Exhibit Paramedic-Like Behavior: Neural Mechanisms Unveiled

UCLA researchers have discovered that mice display prosocial behavior towards unresponsive conspecifics, characterized by intense head-directed grooming. This behavior is driven by an amygdala-regulated response. Experiments showed mice differentiating between sedated and stressed peers, grooming the head of sedated mice and the body of stressed ones. Neural recordings and optogenetic manipulation pinpointed the medial amygdala (MeA) as crucial; silencing MeA GABAergic neurons suppressed head grooming while activation enhanced it. This research illuminates the neural basis of prosocial behavior in mice, offering insights into broader animal social behaviors. This falls under the Tech category.

The Design System Dilemma for Rails Apps in 2025

2025-04-10

Choosing a well-made design system for your application should be a simple task in 2025, yet for Rails apps, it's not. The author, building Business Class, faced this dilemma. Initial attempts with Bulma and Tailwind proved unsatisfactory. The article explores several options: shadcn/ui (requiring Rails integration), daisyUI (lightweight but lacks JavaScript), Flowbite (officially supports Rails, but not fully open-source), Preline (feature-rich, freemium), and RubyUI (built for Ruby, but uses Phlex and requires leaving ERB). Ultimately, the author concludes that continuing with a Tailwind-based approach, either leveraging a pre-built UI library or building a custom theme, is the best path forward.

The Surprising Secrets Hidden in the Entropy of a Mixture

2025-07-01

This article delves into the relationship between the entropy of a mixture of probability density functions and its interpolation factor. The author reveals that entropy, as a function of probabilities, is concave, and this concavity is directly tied to the mutual information between the two distributions. By introducing a Bernoulli variable and the concept of conditional entropy, the article elegantly explains how mutual information quantifies the change in the expected surprisal of a prediction given knowledge of the mixture factor. Furthermore, it introduces a novel concept, 'proclivity', connecting it to KL divergence and cross-entropy. The article also discusses Jensen-Shannon divergence and the Neyman χ² divergence appearing in higher-order Taylor expansions. Ultimately, it concludes that the entropy function of the mixture completely describes the distribution of likelihood ratios between the two probability distributions, offering a fresh perspective on understanding the relationship between probability distributions.
