Impulsive control of a class of multiple unstable neural networks
Journal of Inequalities and Applications, 2021 This paper addresses the issue of stability of a class of multiple unstable Cohen–Grossberg neural networks(CGNNs) under impulsive control. Some novel sufficient conditions are given to make the unstable equilibrium points of the model locally μ-stable ...

Speaker Normalization Using Cortical Strip Maps: A Neural Model for Steady State Vowel Identification [PDF]
, 2007 Auditory signals of speech are speaker-dependent, but representations of language meaning are speaker-independent. Such a transformation enables speech to be understood from different speakers.

Engineering Reports, Volume 8, Issue 1, January 2026.This work tackles the unresolved stability problem of heterogeneous quaternion‐valued BAM neural networks plagued by unknown parameters, time‐varying delays, and impulses. By synergizing Lyapunov theory with inequality techniques, we establish rigorous, yet practical, global stability conditions.

Bifurcation of a Cohen-Grossberg Neural Network with Discrete Delays
Abstract and Applied Analysis, 2012 A simple Cohen-Grossberg neural network with discrete delays is investigated in this paper. The existence of local Hopf bifurcations is first considered by choosing the appropriate bifurcation parameter, and then explicit formulas are given to determine ...

Updates and future perspectives on neuropsychiatric symptoms in Alzheimer's disease
Alzheimer's &Dementia, Volume 21, Issue 3, March 2025.Abstract Neuropsychiatric symptoms (NPS) are common throughout the Alzheimer's disease (AD) continuum and profoundly affect patients, caregivers, and health‐care systems. This review synthesizes key research presented in the 2022 and 2023 Alzheimer's Association International Society to Advance Alzheimer's Research and Treatment Neuropsychiatric ...

New Stabilization Method for Delayed Discrete-Time Cohen–Grossberg BAM Neural Networks
IEEE Access, 2020 This paper deals with the state feedback stabilization problem of delayed discrete-time Cohen-Grossberg BAM neural networks. By the mathematical induction method, stabilizable conditions are derived to ensure that the resulting closed-loop system is ...

Resonant Neural Dynamics of Speech Perception [PDF]
, 2002 What is the neural representation of a speech code as it evolves in time? How do listeners integrate temporally distributed phonemic information across hundreds of milliseconds, even backwards in time, into coherent representations of syllables and words?
