Social and Affective Neuroscience of Everyday Human Interaction
I found – rather serendipitous – this recent, open access and very interesting book “Social and Affective Neuroscience of Everyday Human Interaction“, edited by Springer 2023. This Open Access book presents the current state of the art knowledge on social and affective neuroscience based on empirical findings. Some highlights as appetiser: Molecular Imaging of the…

Bayesian Nonlinear Models
The review article Bayesian Nonlinear Models for Repeated Measurement Data gives a valuation of the use for the Bayesian Model to solve complex problems. Nonlinear mixed effects models have become a standard platform for analysis when data is in the form of continuous and repeated measurements of subjects from a population of interest, while temporal…

Cardiac activity: its role in perception and action
Patterns of cardiac activity continuously vary with environmentaldemands, accelerating or decelerating depending on circumstances. Simultaneously, cardiac cycle affects a host of higher-order processes, where systolic baroreceptor activation largely impairs processing. However, a unified functional perspective on the role of cardiac signal in perception and action has been lacking. — Patterns of cardiac activity continuously vary…

The Art of Abduction
Abductive reasoning typically begins with an incomplete set of observations and proceeds to the likeliest possible explanation for the set. Abductive reasoning yields the kind of daily decision-making that does its best with the information at hand, which often is incomplete. A medical diagnosis is an application of abductive reasoning: given this set of symptoms,…

Prediction: multi-scale pattern completion of the future
The notion of the brain as a prediction machine has been extremely influential and productive in cognitive sciences.One prominent framework is of a “Bayesian brain” that explicitly generates predictions and uses resultant errors to guide adaptation. The prediction-generation component of this framework may involve little more than a pattern completion process. Brain-like systems can get…

Beliefs and Inference
Beliefs are propositions about the true states of the world.Active inference—a process theory based on the free energy principle—describes how an agent forms and updates beliefs.The active inference framework posits that the agent (i) observes the world, (ii) infers the causes of the observations, and (iii) forms beliefs about the external states of the world.…
