Interactive Demonstrations
Interactive visualizations of cognitive neuroscience concepts — ERP components, experimental paradigms, and the neural signatures of cognition.
Parietal ERP: Expected vs. Unexpected
An animated ERP visualization of the P300 oddball paradigm. Rare deviant stimuli elicit a dramatically larger late positive component — a hallmark of context updating in working memory. Clickable component badges reveal latency, generator, and modulation details.
Open →Language ERPs: N400 & P600
Visualizes the N400 and P600 components elicited by semantic and syntactic violations. Demonstrates their classic double dissociation, supporting distinct neural substrates for meaning and grammatical structure in language comprehension.
Open →Bloch Sphere Quantum Simulator
An interactive 3-tab quantum simulator: explore the Bloch sphere with 8 single-qubit gates, visualize Bell-state entanglement between two qubits, and build circuits with a drag-and-drop circuit builder.
Open →CRISPR-Cas9: Programmable DNA Cleavage
An animated, stage-by-stage visualization of the CRISPR-Cas9 mechanism — RNP surveillance, PAM recognition, R-loop formation, double-strand break, and NHEJ vs. HDR repair. Clickable domain badges reveal mechanistic detail and primary literature.
Open →Core Psychophysics
An interactive gallery of four foundational psychophysics findings: Signal Detection Theory (d′ and criterion), Speed-Accuracy Tradeoff, Stevens' Power Law across six sensory modalities, and Hick's Law — each with live parameter controls and primary literature references.
Open →Schneider & Shiffrin (1977): Automatic vs. Controlled Processing
An interactive replication of the classic visual search paradigm. Run consistent-mapping and varied-mapping blocks and watch the RT × set-size slope flatten with consistent mapping — the signature of automaticity that defined a generation of attention research.
Open →Source to Scalp: The EEG Forward Problem
An interactive demonstration of how a cortical current dipole projects to scalp electrodes. Drag the source, rotate its orientation, and toggle skull blurring to see why scalp EEG is spatially smeared and why radial vs. tangential dipoles produce strikingly different topographies.
Open →Spike-Timing Dependent Plasticity
An animated visualization of the STDP learning rule (Bi & Poo, 1998). Set the pre/post spike interval Δt, fire pairs, and watch synaptic weight potentiate or depress. The NMDA receptor acts as the molecular coincidence detector — causal order determines synaptic fate.
