anterogradisena

Anterogradisena is a speculative term used in neuroscience and cognitive science to denote forward-directed transmission of information within a system. It refers to unidirectional signal flow from lower to higher levels of processing or from input toward an output, rather than to a specific, fixed mechanism. The term is commonly employed as a conceptual umbrella for discussions of feedforward dynamics and forward information propagation.

The word is a neologism formed from ante- (forward or before) and grad- (step or degree), with a noun suffix -sena. It is typically contrasted with hypothetical retrogradisena, a notional opposite concept describing backward or feedback-like signaling, though neither term has a universally accepted formal definition.

In neuroscience discourse, anterogradisena is used to describe forward pathways in sensory hierarchies, where information progresses from primary processing regions to higher-order areas. It is often discussed in relation to models of rapid, forward transmission and to frameworks such as predictive coding, which also incorporate feedback signals but reserve emphasis for forward flow in certain contexts.

In artificial intelligence and machine learning, the term has appeared in speculative or pedagogical writing to signify the forward pass of information through a neural network, highlighting representation generation from inputs. Conventional terminology, however, typically uses forward propagation or the forward pass for this idea, while reserving terms like backpropagation for learning.

Status and reception: anterogradisena is not an established term with a standardized definition and is used inconsistently across sources. Caution is advised when encountering the term, and definitions should be clarified within their specific context. Related concepts include anterograde transport, anterograde amnesia, feedforward neural networks, forward propagation, and predictive coding.
