This study investigates the intrinsic organization of axons and dendrites of aspinous, local circuit neurons of the macaque monkey visual striate cortex. These investigations use Golgi Rapid preparations of cortical tissue from monkeys aged 3 weeks postnatal to adult. We have earlier (Lund, ’87) described local circuit neurons found within laminae 5A and 4C; this present account is of neurons f...

Solution to Exercise 4: Communication Protocol

1. A simple network consisting of two nodes, X and Z is shown in Fig 1. The nodes are separated by a distance of L = 800 m, and each node has a single frame of F = 1500 bits (including all headers and preambles) to send to each other. Both nodes attempt to transmit at time t = 0. In case that a node detects a collision, the node executes the exponential back-off algorithm. In the exponential ba...

4. Communication within a Neural Network

Recent observations of complex sequences of neuronal activity, at the level of both synaptic transmission and action potential generation amongst simultaneously sampled multiple neurons, have demonstrated that such patterns can occur spontaneously in the brain. Using multielectrode array (MEA) technology we have sampled simultaneously from a large number of neurons (typically >100 neurons), acr...

A Novel Compression Scheme for Mpeg-4 Headers for Visual Communication

Overheads associated with MPEG-4 video compressed packets reduce bandwidth efficiency. Mobile operators may save a significant percentage of the required bandwidth using IP header compression technologies, and thereby reduce necessary investments. In this paper, a novel header compression scheme for MPEG-4 video packets is proposed and analysed. It is designed to complement existing IP header c...
