- Gorski et al (1978) studied early hormonal effects on sex differences in brain anatomy in rats. What specific area and feature did they study?When Sperry and colleagues ablated the dorsal RGCs, the remaining ventral RGCs projected to the dorsal tectum. Conversely, when they ablated the ventral RGCs, the remaining dorsal RGCs projected to the ventral tectum.Ephrins and Ephs are distributed in dorsoventral gradients in both structures. EphB1 is expressed in the tectum, in a low-dorsal to high-ventral gradient. Ephrin-B1 and ephrin-B2 are expressed in the retina in a high-dorsal to low-ventral gradient. What do these expression patterns suggest about the mechanism used for dorsoventral patterning of RGCs projecting to the tectum?"The tool that the choice architect uses for the myopic procrastination problem is decision staging". Is this statement True or False? O True O False
- An experiment was carried out to investigate proximate mechanisms of behavioural phase change in the locust Locusta fictiva (Figure 2 below). Solitarious locusts were injected with XDA, a dopamine receptor antagonist, either 1 h before or immediately after crowding them for 4 h (N=30 each). A control group of solitarious locusts received a saline injection 1 h before crowding (N=30). Locusts of all three groups were then observed in a behavioural arena to determine their probability of gregariousness (Pgreg). Briefly describe the result and discuss what conclusions you can draw about the proximate mechanism of phase change in this species.Selective serotonin reuptake inhibitors (SSRIs) are drugs that can alleviate symptoms of depression by blocking the reuptake of serotonin (5-HT) from the synaptic cleft, thereby increasing the amount of time that 5-HT remains active. Elevated levels of 5-HT within the synapse are associated with feelings of well-being; conversely, low levels of 5-HT are correlated with depressive symptoms. Recent studies have shown that SSRIs can also mediate their antidepressant effects by increasing brain levels of certain cytokines, including interferon gamma (IFNY). IFNY directly induces the expression of the protein p11 in neighboring neurons, which then interacts with 5-HTR4, a 5-HT transmembrane receptor. Figures 1 and 2 provide information about this interaction. 5-HTR4 protein (% of WT) expression CAMP levels (% change control) from 120T 100+ 80+ 60+ 40+ 20+ 0 MEM TOT Figure 1 5-HTR4 protein expression in plasma membrane-enriched fraction (MEM) of hippocampal lysate and in total hippocampal…What is attenuation?
