Synaptic weight and k scaling

Created by: didi-hou

• Tested the MAM in both ground state and metastable state with K_scaling being tuned
• Changed the y-axis label from 2 3E and 2 3I to 2/3E and 2/3I
• A pad distance was added between the title and plot in the Instantaneous and mean firing rate across all populations plot
• The title of interareal connectivity plot was updated from Interareal connectivity for full-scale (left) and down-scale (right) multi-area model to Interareal probabilistic connectivity for full-scale (left) and down-scaled (right) multi-area model
• Changed the color scheme in the interareal connectivity plot
• Reran the notebook
