Computer-Mediated Communication (CMC) blends verbal, non-verbal, written, visual, and interpersonal communication in the digital space . Online tools like messaging apps and video calls enable these interactions, often altering how we convey and interpret cues. Theories like Communication Accommodation Theory explain how we adjust our tone or style to connect with others online. Meanwhile, models like Lasswell's, Schramm's, and Shannon-Weaver's offer frameworks for understanding message...

Explore the hidden costs of our digital lives, where convenience meets chaos. Cyberpsychology digs into the psychological and physical fallout of our screen time. The Dark Side of Digital: Internet Obsession: When online life overshadows reality. Virtual Vice: Cybersex addiction – a secret struggle. Phone Panic (Nomophobia): Anxiety without a signal. Gaming Overload (IGD): When playtime turns toxic. Typing Tails: Carpal tunnel – the price of endless clicks. Screen Strain: Eyes gl...

Neurons chat at synapses, tiny junctions where one cell’s axon terminal meets another’s dendrite (or cell body). When an electrical signal (action potential) hits the terminal, it triggers vesicles to release neurotransmitters into the synaptic cleft. These chemicals bind to receptors on the next neuron, sparking (or stopping) a new signal. Structure of Synapses: - Presynaptic terminal (sends signal) - Synaptic cleft (tiny gap) - Postsynaptic membrane (receives signal) Types of Syna...

The nervous system is built from neurons, the electric messengers that send and receive signals, and glial cells, the behind-the-scenes support crew. A neuron has three main parts: the cell body (soma) with a nucleus, dendrites that receive input, and an axon that sends signals. Inside, you’ll find mitochondria (energy), endoplasmic reticulum (protein factory), and microtubules(transport tracks). Glial cells (like astrocytes, oligodendrocytes, and microglia) protect, nourish, and insulate neur...

Explore how people think, feel, and act in digital spaces. Covers scope of cyber psychology, online behavior, digital identity, and mental health. Learn to conduct primary research(surveys, experiments) and secondary research (analyzing existing data). Emphasizes ethics: privacy, consent, and data protection online. A modern look at human behavior in cyberspace.

Epilepsy is a neurological disorder causing recurrent seizures due to abnormal brain activity. It’s managed with medication, lifestyle care, and sometimes surgery. Most people with epilepsy can live normal lives with proper treatment.

Cyberpsychology is the study of how people think, feel, and behave online. It looks at how we interact with technology, social media, virtual worlds, and digital devices. It explores topics like online identity, digital addiction, cyberbullying, and how people form relationships on the internet. It also studies how our minds are affected by screen time, gaming, and virtual reality. Basically, it’s psychology applied to the digital world, helping us understand how humans adapt to and are influe...
