<｜begin▁of▁sentence｜>### Instruction:
In the context of studying neural pathways within a specimen, imagine we have observed a simplified model of neural connectivity, presented through a directional connection map comprising of the following connections: neuron 1 to neuron 2, neuron 2 to neuron 3, and neuron 3 to neuron 4. As a physiologist working on understanding the complex interrelations and functional groupings within this neural network, how could one identify all potential trios of neurons (sets of 3 neurons) that could possibly represent a functional unit or sub-network within this system? This inquiry aims to dissect the network's structure to better understand the intricate processes governing neural function and information flow.
### Response:
import networkx as nx
# Create a directed graph
G = nx.DiGraph()
# Add edges
G.add_edges_from([(1, 2), (2, 3), (3, 4)])
# Generate all possible triplets
triplets = list(nx.all_triplets(G))
print(triplets)
