We are witnessing an explosion in the development and adoption of artificial intelligence (AI) technologies. Large language models (LLMs) are trained on the statistical regularities of language to produce humanlike responses.

However, LLMs give obsequious replies, perhaps by dint of their training (with human raters in the loop, who may favor agreeable responses and bots), and can readily dupe their interlocutors into believing they are intentional, even conscious, agents.

They also hallucinate, generating false information in response to prompts (though calling these errors hallucinations is not accurate, since the models do not perceive; it is more accurate to call their errors confabulations).

Unleashing an inaccurate but compelling technology on an unprepared public could dramatically impact mental health.

There have been numerous reports of people developing psychosis after interacting with large language models.

This article implores clinicians to consider whether artificial intelligence models may induce delusionlike beliefs—and how to help overcome this phenomenon.

Junyue Cao, a cell biologist at Rockefeller University in New York City, analyzed gene expression in millions of mouse cells from different life stages. He was surprised to find that “changes in aging are not universal across all the cells,” he said.

By deciphering the molecular signatures of millions of mouse cells, Junyue Cao has found that aging is not haphazard wear and tear but rather a “remodeling of the cell society.”

A recent study published in Nature Mental Health identifies a core set of elements that make up positive mental health, offering a standardized framework to define what it means to truly be well. By consulting experts across multiple disciplines, the research outlines nineteen specific dimensions, ranging from life satisfaction to social connection. The findings provide a foundation for creating more consistent strategies to support and measure psychological well-being in communities and workplaces.

The Top Six Dimensions

Meaning and purpose: Having clear goals, a sense of direction, and a larger aim in life and/or the feeling that what we do is worthwhile, rewarding, and valuable.

Life satisfaction: The degree to which a person positively evaluates the overall quality of their life as a whole (i.e., how much the person likes the life they lead).

Self-acceptance: Experiencing different aspects of oneself (e.g., one’s body, personality, thoughts, and feelings) in a positive, tolerant, receptive, or non-judgmental way; experiencing positive self-worth.

Connection: Involving a feeling of belonging, mutual caring, love, and closeness to friends, family, and loved ones.

Autonomy: The perception that we have ownership over our behavior and choices, and the ability to express oneself.

Happiness: States that are characterized by moderate-arousal pleasant feelings, such as feeling happy, cheerful, and pleased.

The Remaining 13 Dimensions

Acceptance: The ability to self-reflect, identify what is within a person’s control, and accept what is outside one’s control.

Achievement: Having done something successfully, using one’s own efforts and skills.

Activities and functioning: Overall satisfaction with our activities and leisure, and our ability to undertake these tasks.
Belonging: The feeling of deep connection with social groups, physical places, and individual and collective experiences.

Calmness: States characterized by low-arousal pleasant feelings, like serenity and peacefulness.

Competence: Feeling and perceiving oneself as effective and able to overcome challenges and stressors, and achieve desired outcomes.

Development: Experiencing growth and improvement.

Engagement: Having an absorbing experience in which the individual is completely focused on the task at hand or experiencing a state of mindful awareness.

Fun: Experiencing light-hearted pleasure, enjoyment, or amusement; entertainment.

Optimism: Having a positive outlook on life, and positive expectations about the future.

Self-congruence: The perception that our actions and behaviors are compatible with our interests, values, and beliefs.

Sense of safety: The feeling of relative security in one’s daily life.

Vitality: States characterized by high-arousal pleasant feelings, such as feeling energetic and lively.

A recent study published in Nature Mental Health identifies 19 core dimensions of positive mental health. By consulting experts across multiple disciplines, the research offers a standardized framework to define and measure what it means to be truly well.

The main point of the research is called “informational tuning in cortical travelling waves.” The cortex is the surface of the brain that has ridges and furrows. The electrical signals, which travel across it, take the shape of waves. These waves carry information much like how a radio signal carries music, but they can also be “tuned” to hold certain types of information such as sound waves.
Under normal conditions, when a brain is awake and in a normal state of consciousness, these travelling waves are organised in such a way that they allow for effective communication and information transfer between different brain regions. This allows for normal perception, attention, and consciousness. When the brain is under anaesthesia, consciousness is lost, and the question this study poses is whether these travelling waves, responsible for transferring information between different parts of the brain, lose their information-organising ability, possibly leading to loss of consciousness.
In simplest terms, the hypothesis is that consciousness arises not merely from the strength of neural oscillations but from their fidelity to the information content, like a radio signal not just being powerful but properly tuned to the station it aims to receive.

Our consciousness is something that we are constantly aware of, but it actually has to work to do it. The study published in Neuroscience News works to understand the patterns that make us aware and how they change when we are put under anaesthesia. These patterns, called
