 The first step consists of feeding two neural models simultaneously, namely $M_{\Delta}$ and $M_c$, with the camera positional information. The output of these models encodes the positional information from the input image. Although the input is the same, the neural models do not share weights and follow a different flow in the next steps.
 
 ### Cognitive Filtering
-This step performs a series of operations, called \emph{filters}, that work on the embeddings coming from the previous step. There are four filters this step derives: density, color, memory, and modulation.

 ### Memory Updating
-Updating the memory requires the implementation of a mechanism capable of obliterating trivial information, which is performed using the memory filter (Step 3.1 in Figure~\ref{f.bionerf}). Fist, one needs to compute a signal modulation **$\mu$**, for further introducing new experiences in the memory **$\Psi$** through the modulating variable **$\mu$** using a $\textit{tanh}$ function (Step 3.2 in the figure).

 ### Contextual Inference
-This step is responsible for adding contextual information to BioNeRF. Two new embeddings are generate, i.e., **${h}^{\prime}_\Delta$** and **${h}^{\prime}_c$** based on density and color filters, respectively (Step 4 in the figure), which further feed two neural models, i.e., $M^\prime_\Delta$ and $M^{\prime}$. Subsequently, $M^{\prime}_\Delta$ outputs the volume density, while color information is predicted by $M^{\prime}_c$, further used to compute the final predicted pixel information and the loss function.
