Text Solution
AI Generated Solution
The correct Answer is:
**Step-by-Step Solution:**
1. **Identify the Area of the Brain**: The question asks about a specific area of the brain involved in sexual behavior, motivation, and emotional reactions.
2. **Understand the Functions**: The brain structures mentioned (amygdala and hippocampus) are known for their roles in processing emotions and memory. The amygdala is primarily associated with emotions like fear and pleasure, while the hippocampus is crucial for memory formation.
3. **Recognize the Group of Structures**: The question refers to a group of associated deep structures, which include the amygdala and hippocampus. These structures are part of a larger system that integrates emotional responses and memory.
4. **Name the System**: The collection of these structures is known as the **limbic system**. The limbic system plays a significant role in emotional regulation, motivation, and certain aspects of behavior.
5. **Location of the Limbic System**: The limbic system is located in the inner part of the cerebral hemisphere, particularly around the temporal lobe and near the thalamus.
6. **Conclusion**: Therefore, the answer to the question is the **limbic system**.
**Final Answer**: The inner part of the cerebral hemisphere involved in sexual behavior, motivation, and emotional reactions, along with associated structures like the amygdala and hippocampus, is the **limbic system**.

The colloidal particles are electrically charged as a indicated by their migration towards cathode or anode under the applied electric field. In a particular colloidal system, all particles carry either positive charge or negative charge. The electric charge on colloidal particles orginate in several ways. According to preferential adsorption theory, the freshly obtained precipitate particles adsorb ions from the dispersion medium, which are common to their lattice and acquire the charge of adsorbed ions. For example, For example, freshly obtained Fe(OH)_(3) precipitated is dispersed, by a little FeCl_(3) , into colloidal solution owing to the adsorption of Fe^(3+) ions in preference. Thus sol particles will be positively charged. In some cases the colloidal particles are aggregates of cations or anions having ampiphilic character. When the ions posses hydrophobic part (hydrocarbon end) as well as hydrophilic part (polar end group), they undergo association in aqueous solution to form particles having colloidal size. The formation of such particles, called micelles plays a very important role in the solubilization of water insoluble substances, (hydrocarbon, oils, fats, grease etc.). In micelles, the polar end groups are directed towards water and the hydrocarbon ends into the centre. The charge on sol particles of proteins depends on the pH. At low pH, the basic group of protein molecule is ionized (protonated) and at higher pH (alkaline medium), the acidic group is ionized. At isoelectric pH, characteristic to the protein, both basix and acidic groups are equally ionized. The stability of colloidal solution is attributed largely to the electric charge of the dispersed particles. This charge causes them to be coagulated or precipitated. On addition of small amount of electrolytes, the ions carrying oppiste charge are adsorbed by sol particles resulting in the neutralization of their charge. When the sol particles either with no charge or reduced charge, come closer due to Brownian movement, they coalesce to form bigger particles resulting in their separation from the dispersion medium. This is what is called coagulating or precipitation of the colloidal solution. The coagulating power of the effective ion, which depend on its charge, is expressed in terms of its coagulating value, defined as its minimum concentration (m mol/L) needed to precipitate a given sol. Which of the following ions would have the minimum coagulating value for sol obtained on peptizing Sn(OH)_(4) by little NaOH solution?
