What the BPCC 102 Solved Question Paper June 2026 Answers
BPCC 102 Biopsychology is the Semester I core course of IGNOU's Bachelor of Arts (Honours) Psychology (BAPCH) that explains how the neuron, the nervous system, the two hemispheres and the hormones shape behaviour. The June 2026 paper tested it in 2 hours for 50 marks, with 8 questions in two sections.
This paper leaned on Blocks 1 and 2. Section I asked about the synapse and neurotransmitters, CNS disorders, the spinal cord and the forebrain. Section II moved to cranial and spinal nerves, the left and right hemispheres, the pituitary and thyroid glands, and short notes on neuroplasticity and the divisions of the subject.
Two parts were fresh. Research ethics came as the 3-mark half of Question 1, a topic missing from all seven earlier term-end papers we checked, and neuroplasticity returned as a short note. Our IGNOU BPCC 102 Solved Question Paper answers both in the language of the BPCC-102 book, so nothing reads like an outside source.
If you are revising your other first-semester courses at the same time, the BAPCH Question Paper collection keeps every core paper of the programme in one place.
BPCC 102 Biopsychology Sample Answers from the June 2026 Paper
Question 2 and Question 6 are answered in full below, written in the same structure and depth as every answer in the paid file. We picked one question from each section: Question 2 tests the synapse and neurotransmitters for 6+4 marks, and Question 6 tests hemispheric functions and lateralisation methods for 10 marks.
Both topics are regulars in past papers, so reading these two answers is real revision even before you order.
Question 2 Section I 6+4 marks
Question 2 (Section I): Explain the structure of a synapse with the help of a suitable diagram. Describe the neurotransmitters with a focus on their functions. (6+4)
Introduction. A synapse is the junction where one neuron passes a message to another neuron, a muscle or a gland. The term was introduced by the British physiologist Charles Sherrington in 1897. Most synapses in the human brain are chemical, while a smaller number are electrical synapses joined by gap junctions.
(a) Structure of a synapse (6 marks). A chemical synapse has three parts:
- Presynaptic terminal: the swollen end of the axon, called the terminal button. It holds mitochondria for energy and many synaptic vesicles, tiny sacs filled with neurotransmitter.
- Synaptic cleft: a narrow gap of roughly 20 to 40 nanometres between the two cells, which the chemical message has to cross.
- Postsynaptic membrane: the membrane of the receiving dendrite, cell body or axon. It carries receptor proteins that fit particular neurotransmitters, like a lock and key.
Synapses are also named by where they connect: axodendritic (axon to dendrite), axosomatic (axon to cell body) and axoaxonic (axon to axon).
How the synapse works. When an action potential reaches the terminal, voltage-gated calcium channels open and calcium ions flow in. Vesicles fuse with the membrane and release the neurotransmitter by exocytosis. It crosses the cleft, binds to receptors and produces an excitatory (EPSP) or inhibitory (IPSP) potential. The signal ends by reuptake, enzyme breakdown such as acetylcholinesterase, or diffusion.
(b) Neurotransmitters and their functions (4 marks). Neurotransmitters are chemical messengers released at the synapse. The first one identified was acetylcholine, shown by Otto Loewi in 1921. The main neurotransmitters are:
- Acetylcholine: contraction of skeletal muscles at the neuromuscular junction, plus attention and memory; its loss is linked with Alzheimer's disease.
- Dopamine: movement, motivation and reward; too little is seen in Parkinson's disease, and excess activity is linked with schizophrenia.
- Serotonin: mood, sleep, appetite and impulse control; low levels are associated with depression.
- Norepinephrine: alertness, arousal and the fight-or-flight response.
- GABA: the main inhibitory neurotransmitter of the brain; anti-anxiety drugs such as benzodiazepines act on its receptors.
- Glutamate: the main excitatory neurotransmitter, central to learning and memory.
- Endorphins: the body's natural painkillers, released during stress and exercise.
Conclusion. The synapse is where communication in the nervous system actually happens, and the neurotransmitter decides whether the next cell is excited or calmed. That is why most drugs acting on mood, pain or attention work at this chemical step.
Question 6 Section II 10 marks
Question 6 (Section II): Explain left and right hemispheres. Describe the methods to study brain lateralisation. (10)
Introduction. The cerebrum is divided into a left and a right hemisphere by the longitudinal fissure, and the two are joined by the corpus callosum, a band of about 200 million nerve fibres. Each hemisphere controls the opposite side of the body and is better at certain tasks. This specialisation is called lateralisation of function.
Left hemisphere. In about 95 percent of right-handed people the left hemisphere is dominant for language. It holds Broca's area for speech production, described by Paul Broca in 1861, and Wernicke's area for understanding language, described by Carl Wernicke in 1874. It also handles logical and sequential thinking, arithmetic, reading and writing, and controls the right side of the body.
Right hemisphere. The right hemisphere leads in spatial and visual tasks such as reading maps, recognising faces and judging depth. It processes emotional expression, the emotional tone of speech and music, takes a holistic view of patterns, and controls the left side of the body.
The difference is one of degree, not total separation. Both hemispheres share information through the corpus callosum, and most daily tasks use both of them together.
Methods to study brain lateralisation.
- Split-brain studies: Roger Sperry and Michael Gazzaniga studied patients whose corpus callosum had been cut to control epilepsy. Words flashed to the left visual field could not be named, showing that speech sat in the left hemisphere. Sperry received the Nobel Prize in 1981.
- Wada test (sodium amytal test): introduced by Juhn Wada in 1949, it briefly puts one hemisphere to sleep through an injection into one carotid artery, so doctors can see which side controls speech before brain surgery.
- Dichotic listening: different words are played to each ear at the same time. Doreen Kimura (1961) found a right-ear advantage for words, pointing to left-hemisphere language processing.
- Visual half-field presentation: images flashed very briefly to one side of the visual field reach the opposite hemisphere first, so its speed and accuracy can be compared.
- Lesion studies: comparing the effects of damage to each side, as in the patients of Broca and Wernicke.
- Functional neuroimaging: PET and fMRI scans show which hemisphere is more active during a given task.
Conclusion. Lateralisation shows that the two halves of the brain are partners with different strengths. Split-brain research, the Wada test and modern imaging together give the clearest picture of how these roles are divided.
