Communications of the IIMA

Fuzzy inference systems have demonstrated considerable promise for EEG-based cognitive state monitoring in neurodegenerative conditions. However, two design decisions significantly influence system performance and clinical applicability: the choice of inference architecture (Takagi-Sugeno vs Mamdani) and the method of rule and membership function generation (manual expert-driven vs data-driven automated). This paper presents a comparative analysis of both dimensions in the context of an EEG-based Alzheimer’s disease monitoring system operating on the ds004504 OpenNeuro dataset (88 subjects: 36 AD, 23 FTD, 29 HC). A Takagi-Sugeno system, implemented as a hybrid FSM-Fuzzy architecture, is compared against a Mamdani equivalent across four axes: inference …

The Making Of An Extremist: How Do We Become Someone Else’S Nightmare?, María Paula Morales

The Confluence

This article explores how ordinary people can be pulled into extremist movements and what psychological forces drive that process. It looks at three perspectives: social identity theory, which explains how group belonging shapes behavior, identity development, which shows how people searching for meaning may find it in extremist causes; and social neuroscience, which connects radicalization to brain activity linked to fear, loyalty, and moral judgement. Together, these approaches show that radicalization is not simply about ideology but about identity, emotion, and belonging. By understanding these dynamics, we can find better ways to prevent extremism and promote healthier, more inclusive communities.

The Role Of The Ventral Tegmental Area In Reward And Addiction: A Comprehensive Review, Emad Ali Albadawi

Neurosciences

The ventral tegmental area (VTA) is a central hub in reward and motivation, integrating heterogeneous neuronal populations and projection-defined circuits to regulate learning, decision-making, and addiction. This review synthesizes anatomical organization and cellular diversity (dopaminergic, GABAergic, and glutamatergic neurons, including multitransmitter co-release), and maps major efferent pathways constituting the mesolimbic and mesocortical systems. We highlight computational roles of VTA activity, including reward prediction errors, incentive salience, and context memory integration, and summarize drug class-specific mechanisms that perturb VTA output. We then outline time-dependent neuroadaptations across mesocorticolimbic networks and discuss therapeutic implications spanning pharmacological, behavioral, and emerging circuit-targeted interventions. Together, these …

Neuroinflammation At The Crossroads Of Neurodegeneration: The Roles Of Microglia And Astrocytes In Parkinson's Disease, Alzheimer's Disease, And Multiple Sclerosis, Mohannad A. Almikhlafi

Neurosciences

Neuroinflammation plays a critical role in the pathogenesis of neurodegenerative disorders such as Parkinson's disease, Alzheimer's disease, and multiple sclerosis. This review explores the underlying mechanisms of neuroinflammation, with a focus on the roles of microglia, astrocytes, peripheral immune cell infiltration, and cytokine release. The complex interplay between oxidative stress and chronic inflammation accelerates neurodegeneration, contributing to disease progression. Microglial activation, initially protective, becomes harmful when sustained over time, driving chronic inflammation. Similarly, astrocytes once considered passive are now recognized for their active involvement in both inflammatory and neuroprotective responses, depending on their activation state. Prolonged activation of microglia and …
